We have successfully fabricated a single-electron transistor based on undoped Si nanocrystals having radii of approximately 3-5 nm. The energy band structure of the Si dot consists of a set of discrete sublevels and a quasi-continuous band. By self-consistently solving the 3D SchrΓΆdinger and Poisson

β¦ Synopsis
Transport in a silicon single-electron transistor is theoretically studied. By solving a master equation, assuming that the potential barrier has a parabolic potential, we show that the linear conductance has an activated behavior at high temperatures. This result is in quantitative agreement with a recent experimental observation.

A GaAs/Al x Ga 1-x As heterointerface contains charge traps, which can capture and emit a single electron stochastically. We study random telegraph signals (RTSs) from these traps using a single electron tunneling (SET) transistor formed in the heterostructure. The output of the SET transistor switc
