Andreev reflection (AR) is the underlying phenomena that determines the quasiparticle dynamics at the junction of a superconductor with any non-superconducting material, which in turn determines the transport properties of the junction. The tunability of...
Fluctuation or noise may feel undesirable, but can contain intricate detail about a system not accessible by the average of the underlying parameter. In the context of quantum transport in mesoscopic systems, we are interested...
Coulomb drag is a non-invasive tool for probing the interlayer electron-electron interactions in bilayer systems. It is a transport phenomenon where an open circuit voltage (VD) appears in one of the conductors belonging to an...
Transport through edge-channels is responsible for conduction in quantum Hall (QH) phases. The equilibration among the edges dictates the electrical and thermal transport coefficients, and its robust quantization relies on the nature of equilibration: coherent...
Atomically thin p-n junction: The advent of various 2d-materials like graphene, transition metal di-chalcogenides (TMDs) and, the existence of well-established device fabrication technique presented an opportunity to take the solid-state device technology to the atomically...
The emergence of multiple Dirac cones in hexagonal boron nitride (hBN)−graphene heterostructures is particularly attractive because it offers potentially better landscape for higher and versatile transport properties than the primary Dirac cone. However, the transport...
When two-dimensional electron gas is cooled to millikelvin temperature regime and then subjected to a high magnetic field, well resolved Landau levels get developed. For the particulars electron density and magnetic field, electron-electron interactions give...
For a classical capacitor the capacitance is determined by only the geometry, where the electrons distribute themselves such a way that it minimizes the energy. Thus, energy and capacitance are inversely proportional. In quantum mechanics,...
