Thermally stimulated current spectroscopy

Experimental method

Thermally stimulated current (TSC) spectroscopy is an experimental technique which is used to study energy levels in semiconductors or insulators. Energy levels are first filled either by optical or electrical injection usually at a relatively low temperature, subsequently electrons or holes are emitted by heating to a higher temperature. A curve of emitted current will be recorded and plotted against temperature, resulting in a TSC spectrum. By analyzing TSC spectra, information can be obtained regarding energy levels in semiconductors or insulators.
