An intelligent measurement system for diagnosing of semi-insulating materials by photoinduced transient spectroscopy
Résumé
An intelligent measurement system for diagnosing of semi-insulating materials by photoinduced transient spectroscopy has been presented. The system utilises two-dimensional analysis of the photocurrent transients digitally recorded in a broad range of temperatures for determination of defect centers parameters and a simulation procedure for calculation their concentration. The system is shown to be a powerful tool for studies of defect structure of high-resistivity semiconductors.
