Core–shell nanowires

Core–shell nanowires made of Si and Ge can be grown experimentally with excellent control for different sizes of both core and shell. We have studied the structural properties of Si/Ge and Ge/Si core–shell nanowires aligned along the direction, with diameters up to 10.2 nm and varying core to shell ratios, using linear scaling density functional theory in CONQUEST[1].
