About this document
Measuring Semiconductor Band Gap with Probes by Pamula Sindhu is a document available to read on EtoBox.
1. The document describes an experiment to measure the resistivity of semiconductors using a four-probe method. The apparatus included a probe arrangement, a thin germanium crystal sample, a constant current source, and a digital multimeter. 2. Resistivity was calculated using the measured voltage, supplied current, and distance between probes. Temperature and voltage measurements were recorded in a table for the germanium sample. 3. By plotting the logarithm of resistivity versus the inverse of tempera
