Abstract
The Seebeck coefficient of a material measures the magnitude of voltage produced when a temperature gradient is created. This project focused on development of a method for measuring thermoelectric data for material samples in a low temperature setting. Temperatures range from 77 K, the boiling point of liquid nitrogen, to approximately 293 K, room temperature. The technique will be used to measure a sample with a well established measurement of the Seebeck coefficient to establish a baseline. The method will then be used to measure a sample of S_2 Te which has not been thoroughly researched due to its instability at room temperature. The method involved data collection techniques using LabView software as well as creating an integrated chip template to allow switching between samples easily.
