Abstract: We have studied the role of EL2 centers in formation of the photoelectric response of an array of radial $n$-type GaAs/Al$_{x}$Ga$_{1-x}$As ($x$ = 0.3) nanowires (NWs) grown by molecular beam epitaxy on a $p$-type silicon substrate. Results revealed a significant decrease in the time of NW photoresponse recovery as compared to that in a bulk crystal upon the transition of EL2 centers from a metastable nonactive state to the normal ground state.
Keywords: molecular beam epitaxy, semiconductors, nanowires, photoelectric properties, defects, gallium arsenide, silicon.
