Abstract: Abstract Vacancy-type defects in GaN with different carbon concentrations ([C] = 2 × 1016 − 1 × 1018 cm− 3) were probed using monoenergetic positron beams. 1.5-μm-thick GaN layers were grown on Si substrates by metalorganic vapor phase epitaxy. Measurements of Doppler broadening spectra and… read more here.

DOI: 10.1063/1.5026831

Abstract: Defects in the Al2O3(25 nm)/GaN structure were probed by using monoenergetic positron beams. Al2O3 films were deposited on GaN by atomic layer deposition at 300 °C. Temperature treatment above 800 °C leads to the introduction of vacancy-type defects… read more here.
