We report the nondestructive, optical characterization of a heterojunction bipolar transistor (HBT) structure using photoreflectance spectroscopy (PR) and spectral ellipsometry (SE). The PR results show good agreement with capacitance-voltage (C-V) m

Brown trout (Salmo trutta) populations of the three Orkney freshwater lochs—Boardhouse, Harray and Swannay—were studied in late September 1991 using horizontalll oriented sonar. Dual-beam echo counting during mobile surveys gave the following den

The authors present a detailed, first-principle analysis of photoreflectance (PR) spectra using complex Airy functions and their derivatives. With the use of the complex Airy functions, PR spectra directly yield band-gap energies (light and heavy hol
