Alexander Y. Polyakov,N. B. Smirnov,A. V. Govorkov,M.G. Mil’vidskii,Stephen J. Pearton,Alexander Usikov,N. M. Shmidt,Andrei Osinsky,W.V. Lundin,E.E. Zavarin,A.I. Besulkin +10 more
TL;DR: In this paper, the results of microcathodoluminescence (MCL) and deep-level transient spectroscopy (DLTS) studies of AlGaN/GaN modulation doped field effect transistor (MODFET) structures were presented and a strong blue shift in the energy position of the band-edge MCL peak was observed and attributed to screening of the built-in piezoelectric field by the high density of two-dimensional electron gas in the GaN quantum wells.
Journal ArticleDOI
Valence and conduction band offsets in sputtered HfO2/InGaZnO4 heterostructures
TL;DR: In this paper, the authors reported the determination of band offsets in the HfO 2 /InGaZnO 4 heterostructure using X-Ray Photoelectron Spectroscopy.

TL;DR: Ion implantation of Mn or Cr at concentrations of 1-5 at% were performed in AlxGa1−xP (x=024,038) epilayers grown by gas source molecular beam epitaxy Ferromagnetic-like ordering above 100 K for Cr and 300 K for Mn was observed in superconducting quantum interference device measurements.
Journal ArticleDOI
Ohmic contacts to n -type In 0.5 Ga 0.5 P
TL;DR: In this paper, a minimum specific contact resistance of 10−5 Ωcm2 was obtained forn = 2 × 1019 cm−3 material after alloying at 360°C for 20 sec.
