Doped GeSe materials for selector applications

We report on the thermal and electrical performance of nitrogen (N) and carbon (C) doped GeSe thin films for selector applications. Doping of GeSe successfully improved its thermal stability to 450°C. N doping led to a decrease in the off-state leakage and an increase in threshold voltage (Vth), while C doping led to an increase in leakage and reduced Vth. Hence, we show an effective method to tune the electrical parameters of GeSe selectors by using N and C as dopants.
