The effect of doping layers position on the heterojunction sharpness in (In,Al)As/AlAs quantum dots
T. S. Shamirzaev, D. R. Yakovlev, M. Bayer
Effect of doped layer placed in structures with indirect band-gap (In,Al)As/AlAs quantum dots (QDs) on heterointerface sharpness is investigated. We demonstrate that growth of n (p…
