Effects of confinement and orientation on the thermoelectric power factor of silicon nanowires

N Neophytou, H Kosina - Physical Review B—Condensed Matter and …, 2011 - APS
It is suggested that low dimensionality can improve the thermoelectric (TE) power factor of a
device, offering an enhancement of the ZT figure of merit. In this paper, the atomistic sp 3 d 5 …

Transport through an electrostatically defined quantum dot lattice in a two-dimensional electron gas
