Abstract: Passivation capping that enhances the photoluminescence (PL) of molecular beam epitaxy (MBE)-grown InAs surface quantum dots (SQDs) is realized by ex situ low-temperature atomic layer deposition (ALD)-grown Al2O3. As the Al2O3 cap thickness increased from… read more here.

Abstract: Spin interactions between a two-dimensional electron system at the InAs surface and transition metal ions, Fe3+, Co2+, and Ni2+, deposited on the InAs surface, are probed by antilocalization measurements. The spin-dependent quantum interference phenomena underlying… read more here.
