Transition metal dichalcogenides (TMDs) are a family of semiconductors that exhibit a direct bandgap when their thickness is reduced to a monolayer, giving them remarkable optical and electronic properties, including high-efficiency luminescence. Photon emission from these monolayers is investigated using the STM-LE (Light Emission induced by Scanning Tunneling Microscopy) technique. This innovative method involves the localized injection of charge carriers into TMD monolayers through the tunneling current. This process results in the formation of excitons, electron-hole pairs bound by Coulomb forces, within the TMD monolayer. These excitons decay radiatively emitting photons whose energy corresponds to the direct bandgap of the semiconductor. This light emission process is experimentally studied using an STM microscope combined with a light detection system, enabling spectral and spatial analysis of the photon emission with nanometer-scale resolution. The electromagnetic interaction between TMD layers and their metallic substrates leads to the formation of hybrid metal-semiconductor structures, the optical and electronic properties of which are under investigation. The nature of the substrate (plasmonic or non-plasmonic) and its morphology (uniform or nanostructured) play a crucial role in both the intensity and spectral distribution of the emitted photons. Indeed, for plasmonic substrates, the photon emission process involves the electromagnetic coupling between plasmon modes excited by electron tunneling and excitons confined within the TMD monolayer. This interaction leads to an enhancement of the photon emission. Moreover, by tuning the morphology of the substrate, it becomes possible to modify this coupling and thus, the photon emission rate. Considering the significant role of the electromagnetic interaction between plasmon modes and excitons in the luminescence from TMD monolayers within a hybrid TMD/metal-plasmonic STM junction, electromagnetic numerical simulations are carried out using the DDA (Discrete Dipole Approximation) method. These simulations account for electron tunneling using the Quantum Corrected Model. By simulating the optical response of the junction to an incident excitation wave, the electromagnetic modes within the junction and their dependence on the tunneling parameters, such as tip-surface distance and bias voltage, are investigated. In particular, gap plasmon modes and the Fano-type plasmon-exciton coupling at the interface between the monolayer and the plasmon substrate are pointed out. Furthermore, the role of substrate morphology on the properties of these modes is also addressed. Based on theoretical models describing the light emission taking place in purely metallic STM junctions proposed in the literature, a model is developed to compute theoretical light emission spectra for a hybrid TMD/plasmonic-metal STM junction. This model takes into account the optical and electronic properties of the TMD monolayer, and the electron tunneling as the excitation source at the origin of the light emission phenomenon. In addition, using the results obtained from the numerical simulations, the electromagnetic coupling between the excitons confined in the TMD monolayer and the plasmons excited in the nanocavity formed by the tip-surface configuration of the STM is also considered. Finally, the effect of the substrate morphology on the light emission is studied theoretically. These results are compared with the experimental findings in order to validate the model presented

MBA Professional Report
Approved for public release; distribution is unlimited.
The purpose of this MBA project was to determine whether and how VDT can emulate the results obtained from A2C2 Experiments. To do that, we have first focused on learning the basics of VDT and DDD simulation techniques and then on how the models used in DDD can be analyzed using VDT. To this end, we obtained experimental data from DDD Experiment 8 and created representative models in VDT to determine the similarities and differences. We also kept detailed records of our research to assist individuals in the future who may want to expand on our work. The project involved studying of DDD and VDT techniques, establishing building blocks in VDT, creating a best effort model for DDD Experiment 8 and studying the various outcomes. In this project we could not successfully replicate the complex DDD Experiment 8 scenarios within VDT. However, important conclusions were drawn that would go a long way towards helping future studies in this regard.

The ODE- and DDE models are based on the same model with the only exception that the DDE model features reaction times. They are defined by consideration forces and sub-consideration forces. The values (h; k) determines the number of cars that each driver considers and therefore adds to the system as additional terms that are of the same form as the consideration forces, hence the sub prefix. The basic case where there are no sub-considerations involved is called the base case of the system and equals to (h; k) = (1; 1). The (h; k) of the system is determining the matrix B in equation (11) by the number of sub diagonals h and super diagonals k that are filled by weights of the forces. The time integrations can result in three base cases, unstable, stable oscillating and exponentially stable. These cases refer to the behavior of all system velocities. The unstable case can for limited time frames predict collisions between cars but otherwise diverge and cannot generally be used. Oscillating stable systems reach a constant velocity after a settling time and fits well into a realistic scenario. The exponential case reaches a constant velocity the fastest and is therefore the sought after solution. Both models are similar in this regard apart from the fact that the DDE model generally have a lot more system energy. Figures 1 and 4 are empirical proof that the models works as defined and can predict some traffic behavior. An interesting observation during testing was that the ODE exponential case would always remain exponential no matter the multiplication (; ; ) = C(; ; ), the only difference would be the system energy since larger acting forces are coupled with larger energies. The DDE model however is dependent on the system energy for stability since the delay sets a system energy limit for stability since too large forces coupled with delay will not achieve the optimum distance d. The system stability analysis can be reduced in both models to analyzing the homogeneous and particular parts separate. The expansions confirms in both cases what the time integrations shows and can give an idea of how the stability changes with one parameter changing. However, this is where the DDE model behaves completely different from the ODE model. For the ODE case it is possible to plot a complete eigenvalue chart whereas the DDE case has an infinite number of eigenvalues and is therefore impossible to completely chart. A conclusion that is in common between the models is that Fd(t) inherently is dominant and should as such be at lower priority compared to the other consideration forces in order to help system stability. Comparisons to the spring equation revealed that systems that prioritize Fd(t) too high converges to a system of particles in a chain connected by springs with no friction giving the observed behavior. Prioritizing F fr(t) help stability in both cases with the exception that DDE case will be stable for a sub interval (since the top limit comes from the system total energy) within the expansion whereas the ODE case remains stable through the whole intervall. The problems that come with larger systems are stability- and computation complexity related. All through the project has the models focused on the base case with no sub-considerations. The thesis is that adding sub-considerations will again stabilize an unstable system with the addition that each consecutive weight should deflate its value exponentially. The results proves that an unstable system can be stabilized by simply increasing the (h; k) of the system. This can have applications when the optimal weights are not enough to stabilize a large system. When computing the eigenvalues for large systems it puts strain on the algorithm ’eig’. According to [1] is the computation time complexity proportional to n3. What the resulting fit shows is that the relation is more quadratic than cubic and the reason is described to be the appearance of the system matrix for the base case. The matrix structure is similar to the one of the upper Hessenbergs which as a result saves time when transforming the input matrix which is the reason why the complexity is weakly cubic.
