Abstract

This paper describes some novel techniques developed for directly measuring the electron mobility μe and mean free drift time Te in wide band gap semiconductors. These methods are based on a newly-developed digital data analysis system, in conjunction with single carrier charge sensing and depth sensing techniques. Compared with conventional methods, the new techniques are easier to implement, do not involve curve fitting, allow the use of high energy γ-rays and are not sensitive to variations in pulse rise time.
