Abstract:

The interface between two wide band-gap insulators, LaAlO3 and SrTiO3 (LAO/STO), hosts a quasi-two-dimensional electron gas (q2DEG), two-dimensional superconductivity, ferromagnetism, and giant Rashba spin-orbit coupling. The co-existence of two-dimensional superconductivity with gate-tunable spin-orbit coupling and multiband occupation is of particular interest for the realization of unconventional superconducting pairing. To investigate the symmetry of the superconducting order parameter, phase sensitive measurements of the Josephson effect are required. We describe an approach for the fabri

Abstract:

In organic electronics, conjugated conductive polymers are most widely used. The scope of their application is currently very wide. Non-conjugated polymers are used much less in electronics and are usually used as insulation materials or materials for capacitors. However, the potential of non-conjugated polymers is much wider, due to the fact that new electronic materials with unique electronic properties can be created on the basis of non-conjugated polymers, as well as other inorganic dielectrics. This article demonstrates the possibilities of creating electrically conductive materials with

Abstract:

The dynamics of a quasi-two-dimensional electron system (q2DES) in the presence of a tilted magnetic field is reconsidered employing the thin-layer method. We derive the effective equations for relativistic and nonrelativistic q2DESs. Through a perturbative expansion, we show that while the magnetic length is much greater than the confinement width, the in-plane magnetic field only affects the particle dynamics through the spin. Therefore, effects due to an in-plane magnetic vector potential reported previously in the literature for 2D quantum rings, 2D quantum dots and graphene are fictitious

Abstract:

Data from the Census Bureau's Annual Report on Poverty show that 37.4 million Americans—two million more than the previous year—had no health insurance during 1992. The proportion of people with no health insurance also increased from 14.1 percent in 1991 to 14.7 percent in 1992. This is the largest annual increase—both in the number of people and the proportion of the population lacking health care coverage—since 1987, the first year for which comparable data are available. In 1987, the Census data show, 31 million people—12.9 percent of the population—were not covered by health insurance. Bo

Abstract:

AbstractMulti-orbital physics in quasi-two-dimensional electron gases (q2DEGs) triggers intriguing phenomena not observed in bulk materials, such as unconventional superconductivity and magnetism. Here, we investigate the mechanism of orbital selective switching of the spin-polarization in the oxide q2DEG formed at the (001) interface between the LaAlO3, EuTiO3 and SrTiO3 band insulators. By using density functional theory calculations, transport, magnetic and x-ray spectroscopy measurements, we find that the filling of titanium-bands with 3dxz/3dyz orbital character in the EuTiO3 layer and at

Abstract:

Abstract In this work, we investigate the impacts of the temperature-dependent screening effect on the Seebeck coefficient originating from the phonon drag, namely phonon – drag thermopower Sg, of a double layer system consisting of bilayer graphene (BLG) separated from a quasi-two-dimensional electron gas (q2DEG) by an air medium (hereafter referred to as BLG-q2DEG). For such a system, we can assume that the two-dimensional (2D) electrons in BLG only interact internally with acoustic phonons. We consider the effects of screening induced by the 2D electrons in q2DEG on the electron-phonon inte

Abstract:

The ratio of the scattering and single-particle relaxation time of a quasi-two-dimensional electron gas (Q2DEG) in a finite lattice-mismatched GaAs/InGaAs/GaAs quantum well was investigate at zero and finite temperatures, taking into account the exchange-correlation effects via a local-field correction with three approximations for the LFC, G = 0, GH, and GGA. We studied the dependence of the surface roughness, roughness-induced piezoelectric, remote and homogenous background charged impurity scattering on the carrier density and quantum well width.

Abstract:

In condensed matter physics, the concepts of topology and symmetry are of paramount importance, particularly in understanding quantum phase transitions. Topology classifies objects based on their topological properties, which are properties that are preserved under continuous deformation. This is relevant to a wide range of phenomena, such as topological insulators and the quantum Hall effect. On the other hand, symmetry is used to understand phase transitions, where a higher symmetry group is broken into a lower symmetry subgroup. The study of quantum phases and phase transitions is a fun
