What is Band Gap Determination of Thermistor about?

This document provides instructions for an experiment to determine the band gap of a semiconductor material using a post office box circuit. The experiment uses a thermistor, power supply, galvanometer and resistors in a Wheatstone bridge circuit. By balancing the bridge at different temperatures, the resistance of the thermistor as a function of temperature is measured. From this data, a graph of ln(R) versus 1/T is plotted and the band gap is calculated from the slope of the line using the given formula.
