Ga 1-x Al x Sb avalanche photodiodes: Resonant impact ionization with very high ratio of ionization coefficients
TL;DR: In this paper, the authors measured the impact ionization coefficients α (electrons) and β (holes) with different composition and temperature and found a resonant enhancement of the hole ionization coefficient for x = 0.065 (300 K) where the ratio α/α exceeds values of 20.
Journal ArticleDOI
Resonant enhancement of impact in Ga1−xAlxSb
TL;DR: In this article, the impact ionization coefficients α and β of Ga1−xAlxSb avalanche photodiodes were measured for 0⩽x < 0.3.
Journal ArticleDOI
Free and bound electron transitions to acceptors in indium phosphide
TL;DR: In epitaxial InP, a new emission band at 1.3776 eV is identified as the free electron-acceptor transition as discussed by the authors, which permits individual determination of the acceptor and donor binding energies (48 ± 1 meV and 7.3 ± 0.6 meV respectively).

Losses in GaInAs(P)/InP and GaAlSb(As)/GaSb lasers - The influence of the split-off valence band
TL;DR: In this paper, the authors observed the radiative high-energy recombination of electrons with holes in the split-off valence band in GaInAsP/InP lasers.
