Local density approximations from finite systemsThe local density approximation (LDA) constructed through quantum Monte Carlo calculations of the homogeneous electron gas (HEG) is the most common approximation to the exchange-correlation functional in density functional theory....
Transport studies of algan/gan high electron mobility transistor structures... Two dimensional electron gas (2DEG) sheet charge density and 2DEG mobility at room temperature (300K) are studied with the results obtained from theoretical 1D Poisson simulation and Hall effect...
Charge transformer to enhance noise performance of single-electron transistor amplifiers in high-capacitance applications... The operation principle is demonstrated on a prototype charge transformer with four capacitors made using a GaAs/AlGaAs heterostructure with a two-dimensional electron gas....
Giant andreev backscattering through a quantum point contact coupled via a disordered two-dimensional electron gas to superconductorsWe have investigated the superconducting-phase-modulated reduction in the resistance of a ballistic quantum point contact (QPC) connected via a disordered two-dimensional electron gas (2DEG) to superconductors....
