Abstract
A new estimation method which enables one to evaluate the energy depth Et of carrier trap from the 1st order thermally stimulated current (TSC) curve was proposed. In this new method, the peak temperature Tp and the slope of tangential line on any coordinates of Arrhenius plot are utilized availably as the Fundamental Elements. The new method was named as the Slope Estimation Method. This method can be dealed with by computer. This fact enables one to evaluate the Et values even in various observed temperature ranges and to shorten the evaluation time. By utilizing a series of Et values evaluated through the slope of any coordinates, the Tp can be accurately detected and the Et value can be evaluated as exactly as possible in the following step. Additionally, it has been discussed for the first time that the cletection of background noises and their removal were made possible by using the clear standard. These original characteristics involved in the proposal are very useful because there exist some unavoidable errors in any data obtained experimentally.
