Abstract:
A combination of numerical methods for processing of a deep level transient spectroscopy (DLTS) transient signal with continuous distribution in time and in intensity, comprising the steps of:a. converting said DLTS transient signal from one period in a plurality of sampling points, each one of said sampling points representing an averaged intensity of said DLTS signal in a time segment with a constant length from said DLTS signal;b. averaging said sampling points over time intervals, said time intervals combined in time segments, with length of said time segments increasing by the power of two;c. assigning the results of said averaging to a plurality of data points, each data point with a distinct time delay measured from commencement of said one period;d. repeating steps (a) through (c) for a second period of said DLTS periodical signal;e. subtracting each said data point from the period preceding said second period from corresponding data point with same said time delay from said second period;f. dividing each result from said subtracting to a number, said number associated with periodicity of said DLTS periodical signal into a digital time constant of averaging;g. summing each result from said dividing with a corresponding data point with same said time delay from said preceding period; andh. assigning each result from said summing to a corresponding data point with same said time delay from said second period.
