Hydrogen trapping at surface and subsurface vacancies of low-index surfaces of Pd
A. V. Subashiev, H. H. Nee
Hydrogen segregation to vacancies in the surface and subsurface layers of (111) and (100) surfaces of Pd is studied in the density functional theory (DFT) approach. Adsorption ener…
Effects of thermal treatment on radiative properties of HVPE grown InP layers
Serge Luryi, Oleg Semyonov, Arsen Subashiev +5
Radiative efficiency of highly luminescent bulk InP wafers severely degrades upon heat treatment involved in epitaxial growth of quaternary layers and fabrication of photodiodes on…
Edge excitation geometry for studying intrinsic emission spectra of bulk n-InP
Oleg Semyonov, Arsen Subashiev, Zhichao Chen +1
The shape of the photoluminescence line excited at an edge face of InP wafer and recorded from the broadside is used to investigate the intrinsic emission spectrum. The procedure i…
Temperature controlled Lévy flights of minority carriers in photoexcited bulk n-InP
Arsen V. Subashiev, Oleg Semyonov, Zhichao Chen +1
We study the spatial distribution of minority carriers arising from their anomalous photon-assisted diffusion upon photo-excitation at an edge of n-InP slab for temperatures rangin…
Levy Flight of Photoexcited Minority Carriers in Moderately Doped Semiconductors: Theory and Observation
Arsen Subashiev, Serge Luryi
Spatial spread of minority carriers produced by optical excitation in semiconductors is usually well described by a diffusion equation. The classical diffusion process can be viewe…
Direct observation of Levy flight of holes in bulk n-InP
Serge Luryi, Oleg Semyonov, Arsen Subashiev +1
We study the photoluminescence spectra excited at an edge side of n-InP slabs and observed from the broadside. In a moderately doped sample the intensity drops off as a power-law f…
