Control of grain size in sublimation-grown CdTe, and the improvement in performance of devices with systematically increased grain size [PDF]

, 2010
A method to control the grain size of CdTe thin films deposited by close space sublimation using chamber pressure is demonstrated. Grain diameter is shown to increase in the pressure range 2–200 Torr, following the linear relationship D (?m)=0.027×P ...
