Resistivity & Band gap Measurement

Description: Resistivity & Band gap Measurement Resistivity and Band Gap Measurement of semiconductor is a versatile and useful system for physics and basic electronics laboratories. In Nvis 6105, Band Gap can be measured by using Four Probe Method. This is one of the widely used methods for measuring the Resistivity and Band Gap of semiconductors. A collinear four-probe arrangement has been used. In this system, we provide the pressure contacts with sample to take quick measurement on different positions. The setup is equipped with microcontroller based display for simultaneous measurement of voltage, current and temperature. Computer interfacing helps in automatic calculations and analysis. A complete setup for measuring the Resistivity and Band Gap Four individually spring loaded probe arrangement is provided Collinear and equally spaced probes LCD Display The probes are mounted in a Teflon bush, which ensure a good electrical insulation between the probes PC Interfacing using USB/RS232 ports and supporting software is provided Sample-Germanium crystal Learning material CD
