Optical properties of a spherical 2D electron gas in the presence of a uniform magnetic field
… RPA, we calculate the plasmon frequencies of an electron gas on a two-dimensional spherical surface in the presence of a weak magnetic field. We show that the magnetic field results in a coupling between electronic states with different angular momentum numbers. This coupling results in a …

Nonlinear transport in two-dimensional electron gas at large filling factors.
… nonlinear electrical transport in high-mobility 2D electron gas (2DEG) forming in modulation-doped GaAs/AlGaAs quantum wells. Transport nonlinearities induced by a pure dc electric field as well as by coexisting dc and microwave fields were studied at very high Landau level filling factors. It …

Gallium nitride MEMS resonators
… increasingly used in high-power, high-frequency electronics and monolithic microwave integrated circuits (MMICs). At the same time, GaN also has excellent electromechanical properties, such as high acoustic velocities and low elastic losses. Together with a strong piezoelectric coupling, these …

2D Electron Systems in Undoped GaAs and InGaAs and Progress Towards Undoped GaAs Nano-Structures
… Quantum Hall and Fractional Quantum Hall in a 2D electron system (2DES), 1D transport, and single-electron transport in 0D systems. The wide range of systems that can be studied all start with a 2DES from which 1D and 0D systems are formed by further confining the carrier gas. Undoped devices, …

HYDRODYNAMIC AND BALLISTIC TRANSPORT IN ULTRA-CLEAN 2D ELECTRON SYSTEMS
… in mesoscopic systems, resulting from strong electron-electron interactions. In the first part, we consider electrons are in near thermal equilibrium with each other, and for which case we calculate conductance by solving hydrodynamic equations. We do this for the Corbino and Hall bar …
