Observation of quasi bound states in open quantum wells of cesiated p-doped GaN surfaces

Mylène Sauty, Jean-Philippe Banon, Nicolas M. S. Lopes +4

The electron density of states in the open quantum well formed by the downward band bending region at the surface of cesiated p-type GaN is investigated. We theoretically predict t…

Deep-level structure of the spin-active recombination center in dilute nitrides

A. C. Ulibarri, C. T. K. Lew, S. Q. Lim +5

A Gallium interstitial defect (Ga) is thought to be responsible for the spectacular spin-dependent recombination (SDR) in GaAsN dilute nitride semiconduc…

Nanoscale mapping of sub-gap electroluminescence from step-bunched, oxidized 4H-SiC surfaces

Natalia Alyabyeva, Jacques Ding, Mylène Sauty +7

Scanning tunneling luminescence microscopy (STLM) along with scanning tunneling spectroscopy (STS) is applied to a step-bunched, oxidized 4H-SiC surface prepared on the silicon fac…

Probing local emission properties in InGaN/GaN quantum wells by scanning tunneling luminescence microscopy

Mylène Sauty, Natalia Alyabyeva, Cheyenne Lynsky +7

Scanning tunneling electroluminescence microscopy is performed on a 3-nm-thick InGaN/GaN quantum well with x = 0.23 such that the main light emission occurs in the green. The techn…

Evidence of localization effect on photoelectron transport induced by alloy disorder in nitride semiconductor compounds

Mylène Sauty, Nicolas M. S. Lopes, Jean-Philippe Banon +7

Near-bandgap photoemission spectroscopy experiments were performed on p-GaN and p-InGaN/GaN photocathodes activated to negative electron affinity. The photoemission quantum yield o…
