AUTOMATED COMPLEX FOR MEASUREMENT OF THERMOELECTRIC PARAMETERS OF SEMICONDUCTORS
Keywords:
electrical parameter, semiconductor, automation, microcontroller, installation.Abstract
The method of measuring of electrical parameters (conductivity type, electrical conductivity, Hall coefficient, carrier concentration, mobility, the Seebeck coefficient) of semiconductors has been described. The electrical circuit has been submitted and a computer program has been developed that provides automation of measurement, registration and initial processing of the data with the possibility of charting time dependences for the preliminary analysis of the experimental data which are in the process of measurement. The maximum error of electrical conductivity does not exceed 3%, Hall coefficient – 5%, and Seebeck coefficient – 15%.
