Texte intégralDigitalization of society creates important quantities of data that have been increasing at an exponential rate during the past few years. Despite the tremendous technological progress, digital computers have trouble meeting the demand, especially for challenging tasks involving artificial intelligence or optimization problems. The fundamental reason comes from the architecture of digital computers which separates the processor and memory and slows down computations due to undesired data transfers, the so-called von Neumann bottleneck. To avoid unnecessary data movement, various computing paradigms have been proposed that merge processor and memory such as neuromorphic architectures that take inspiration from the brain and physically implement artificial neural networks. Furthermore, rethinking digital operations and using analog physical laws to compute has the potential to accelerate some tasks at a low energy cost.This dissertation aims to explore an energy-efficient physical computing approach based on analog oscillatory neural networks (ONN). In particular, this dissertation unveils (1) the performances of ONN based on vanadium dioxide oscillating neurons with resistive synapses, (2) a novel mixed-signal and scalable ONN architecture that computes in the analog domain and propagates the information digitally, and (3) how ONNs can tackle combinatorial optimization problems whose complexity scale exponentially with the problem size. The dissertation concludes with discussions of some promising future research directions

Texte intégralFunctional perovskite oxides are of great interest for fundamental and applied research thanks to the numerous physical properties and inherent mechanisms they display. With the maturation of thin film deposition techniques, research teams are able to reproduce oxide films and nanostructures of great crystalline quality with some of the most remarkable properties found in physics, a state leading now to upper-level thoughts like their ability to fulfill industrial needs. This thesis work is an answer to some of the problematics that arise when considering the oxide transition from the research to the industrial world, by focusing on their integration for micromechanical devices (MEMS) such as sensors. In order to ease the access to MEMS manufacturing, it is of importance to allow the deposition of thin oxide films on semiconductor substrates. A first study show that these access bridges can be crossed when using appropriate buffer layers such as SrTiO3 deposited on Silicon or gallium arsenide – produced in close collaboration with INL by Molecular Beam Epitaxy - and yttria-stabilized zirconia directly grown on silicon by pulsed laser deposition, which adapts the surface properties of the substrate to perovksite-based materials. Formation of thin epitaxial and monocristalline films of functional oxides is thus allowed on such buffer layers. As an example, characterization of two mixed-valence manganites La0.80Ba0.20MnO3 and La0.67Sr0.33MnO3 demonstrates that both materials are of excellent crystalline quality on these semiconducting substrates and that their physical characteristics match the one found on classical oxide substrates like SrTiO3. Stress evolution in thin films, which has a major effect in epitaxial materials, is then addressed to quantify its impact on oxide microstructure viability. This work gives an identification of the most significant factors favoring stress generation in the case of the films we produced. Then, based on the deformation measurement of free-standing cantilevers made of manganites on pseudo-substrates, and with the support of appropriate analytical models, a new state of equilibrium is established, giving new information about the evolution of static stress from deposition to MEMS device manufacturing. Solutions to manage their reproducibility is then studied. From another perspective, free-standing microstructures made of monocristaline manganites were used to display the effect of dynamical strain on their electrical resistivity (piezoresistivity) and their inherent structures.Finally, a specific example of the capabilities of reproducible free-standing microbridges made of manganites is presented through the conception of a pressure gauge based on Pirani effect. Indeed, it is shown that the abrupt resistivity change this material exhibits near their metal-to-insulating transition creates high temperature coefficients in standard application environments that can be taken as an advantage to improve the sensibility and power consumption of such gauges whose development had significantly slowed down over the past years. A set of improvements on their sensitivity range and their signal acquisition is also presented. Combined to a specific and innovative package, it is also demonstrated that Pirani gauge capabilities can be enhanced and that the complete devices fulfill embedded application requirements

Texte intégralOs óxidos de vanádio têm sido bastante estudados devido às suas múltiplas formas e fases. Em particular, o VO2 apresenta uma transição metal-isolante (MIT) reversível e ultrarrápida que ocorre a ~68ºC que altera o material de estrutura monoclínica para tetragonal rutile. Um estímulo externo (térmico, químico ou elétrico) pode provocar esta transição, alterando-a de um estado de alta resistência para baixa resistência, significando que pode ser usado como interruptor elétrico. Neste trabalho, foram estudadas as condições ótimas para produzir filmes finos de VO2 (~200 nm de espessura). Foram depositados por e-beam evaporation e rf magnetron sputtering (a diferentes pressões de O2), seguidos de um tratamento RTA a diferentes temperaturas. A composição estrutural dos filmes finos de VO2 foi caracterizada por XRD, XPS e AFM. Os filmes depositados por e-beam não são reproduzíveis devido a contaminações do cadinho de tungsténio e foi difícil evaporar os “pellets” de VO2. Os filmes eram amorfos depois da deposição e o recozimento realizado mostrou que a fase monoclínica de VO2 foi atingida com sucesso a 500ºC. O substrato utilizado foi Vidro/ITO. À medida que a temperatura aumentava e a pressão de O2 diminuía, a cristalização e rugosidade dos filmes aumentava. As condições ótimas por sputtering foi obtida para 3x10-5 mbar de pressão de O2 e temperatura de 450ºC num ambiente de N2 com uma pressão base de 250 mbar. Dispositivos MIM foram fabricados por sputtering onde Molibdénio (Mo) foi o metal depositado por cima do VO2, usando máscaras com contactos circulares e usando filmes de ITO como contacto de baixo. A caracterização in-situ com aquecimento foi realizada no XRD e XPS para se analisar a transição in termos de diferenças de fase assim como as propriedades químicas e elétricas. A caracterização elétrica preliminar foi realizada para explorar a MIT em filmes finos de VO2 otimizados.

Trouver le texte intégralPhase transition materials (PTM) have garnered immense interest in concurrent post-CMOS electronics, due to their unique properties such as - electrically driven abrupt resistance switching, hysteresis, and high selectivity. The phase transitions can be attributed to diverse material-specific phenomena, including- correlated electrons, filamentary ion diffusion, and dimerization. In this research, we explore the application space for these materials through extensive device-circuit co-design and propose new ideas harnessing their unique electrical properties. The abrupt transitions and high selectivity of PTMs enable steep (< 60 mV/decade) switching characteristics in Hyper-FET, a promising post-CMOS transistor. We explore device-circuit co-design methodology for Hyper-FET and identify the criterion for material down-selection. We evaluate the achievable voltage swing, energy-delay trade-off, and noise response for this novel device. In addition to the application in low power logic device, PTMs can actively facilitate non-volatile memory design. We propose a PTM augmented Spin Transfer Torque (STT) MRAM that utilizes selective phase transitions to boost the sense margin and stability of stored data, simultaneously. We show that such selective transitions can also be used to improve other MRAM designs with separate read/write paths, avoiding the possibility of read-write conflicts. Further, we analyze the application of PTMs as selectors in cross-point memories. We establish a general simulation framework for cross-point memory array with PTM based selector. We explore the biasing constraints, develop detailed design methodology, and deduce figures of merit for PTM selectors. We also develop a computationally efficient compact model to estimate the leakage through the sneak paths in a cross-point array. Subsequently, we present a new sense amplifier design utilizing PTM, which offers built-in tunable reference with low power and area demand. Finally, we show that the hysteretic characteristics of unipolar PTMs can be utilized to achieve highly efficient rectification. We validate the idea by demonstrating significant design improvements in a Cockcroft-Walton Multiplier, implemented with TS based rectifiers. We emphasize the need to explore other PTMs with high endurance, thermal stability, and faster switching to enable many more innovative applications in the future.
