    We report AlGaN-based back-illuminated solar-blind ultraviolet p-i-n photodetectors with a peak responsivity of 136 mA/W at 282 nm without bias. This corresponds to a high external quantum efficiency of 60%, which improves to a value as high as 72% under 5 V reverse bias. We attribute the high...

    We have experimentally investigated the radiative and nonradiative recombination in a GaN/AlGaN multiple-quantum-well laser diode. The each carrier lifetime has been evaluated based on a rate equation analysis of light output-current characteristics of the laser diode. The estimated nonradiative...

    We studied the behavior of middle IR GaAs/AlGaAs quantum cascade lasers (QCL) subjected to a strong magnetic field perpendicular to the 2D planes. We observed that both laser threshold and differential quantum efficiency are modulated by a magnetic field. The intersubband lifetime vs magnetic...

    Optical phonons are measured to probe the origins of the reported anomalously high piezoelectric response in aluminum scandium nitride (Al1-xScxN). Epitaxial layers with 0≤x≤0.16 deposited on sapphire(0001) exhibit a refractive index below the band gap, which increases from 2.03 for...

    In Quantum Mechanics, Landau and Lifschitz derive a formula for the direct calculation of rovibronic statistical weights. If it were correct, this formula would dramatically reduce the effort necessary to calculate statistical weights in large molecules. Unfortunately, due to a common...
