This project investigates the thermoelectric behaviour of an undoped zinc oxide (ZnO) pellet through the experimental measurement of its Seebeck coefficient at room temperature. Using a Keysight B2901A Source Measure Unit with silver paste contacts and a resistive heater setup, a controlled temperature gradient was applied across the pellet and the resulting thermoelectric output voltage was recorded across multiple independent runs. By analysing the linear relationship between output voltage and temperature difference, the Seebeck coefficient was extracted and evaluated against established literature values for undoped ZnO. The study also identifies a reproducible threshold behaviour at elevated temperature differences, attributed to grain boundary effects inherent to the polycrystalline pellet structure, and discusses the broader implications of the measured thermoelectric response in the context of ZnO as an n-type semiconducting material.
