Tunable diameter and spacing of double Ge quantum dots using highly-controllable spacers and selective oxidation of SiGe

Abstract We report the novel tunability of the diameters and spacings of paired Ge double quantum dots (DQDs) using nano-spacer technology in combination with selective oxidation of Si0.85Ge0.15 at high temperature. Pairs of spherical-shaped Ge QDs were formed by the selective oxidation of poly-SiGe...
