*Abstract

University of MissouriOffice of Technology Management & Industry RelationsNon-Confidential Abstract of InventionUM Disclosure No. 11UMC022Software-Based Charge Deep Level Transient Spectrometer The present invention is a novel Charge-based Deep Level Transient Spectroscopy (Q-DLTS) system for the characterization of wide bandgap semiconductor materials. This straightforward design takes advantage of the emergence of fast data acquisition cards and modern graphical development environments. This system foregoes all hardware-based data processing in favor of adaptable software-based algorithms. The only necessary electronic components are those essential to integrate and amplify the thermally emitted trapped charge transients, and to provide the timing signals that control each measurement cycle. Trap excitation is achieved via voltage or light stimulation. The software-based algorithm then digitally filters the raw charge data, compensates for spurious input signals, and constructs a Q-DLTS spectrum based upon user-defined input parameters. Trap signature information such as thermal activation energy, capture cross section, and concentration can be obtained.
