We propose and demonstrate a novel concept to address high-performance, extended short wavelength (e-SWIR) photodetectors. Our approach is based on shifting the well-developed GaAs quantum-well infrared photodetector (QWIP) technology to e-SWIR wavel

In this paper, we discuss the design of photovoltaic quantum well infrared photodetectors (QWIPs) based on polar GaN/AlGaN multiquantum wells (MQWs). Getting a reasonable escape probability of the excited electron requires adjusting the bound-to-quas

We demonstrate the first implementation of a GaN-based infrared photodetector epitaxially grown on silicon. The device is a GaN/AlGaN quantum cascade detector that consists of layered quantum well structure grown by plasma-assisted molecular beam epi

We compare the simulations and measurements of gate leakage current in metal-insulator-semiconductor capacitors fabricated on standard AlGaN/GaN transistor layers. In the simulations, a fixed charge density at the interface between the Al 2 O 3 layer

Interatomic Coulombic decay (ICD) is an ionization phenomena that takes place due to the Coulombic electronic repulsion force that correlates the ionized electrons with the other electrons. Here we present an analytical analysis of the ICD in two cou

We study the dark exciton's behavior as a coherent physical two-level spin system (qubit) using an external magnetic field in the Faraday configuration. Our studies are based on polarization-sensitive intensity autocorrelation measurements of the opt
