Description:
In order to fabricate a thermoelectric device on glass substrate for harvesting waste heat energy through house appliances, the Seebeck coefficient of translucent TiO 2 thin film was investigated. The TiO 2 thin film was synthesized by using hydrothermal method with F-SnO 2 coated glass as substrate. From scanning electron microscopy analysis, the synthesized TiO 2 thin film was found to be in nanometer-scale rod structure with a thickness of 4 µm. The Seebeck coefficient was measured in the temperature range of 300 – 400 K. The Seebeck coefficient is found to be in negative value which shows that synthesized film is an n-type semiconductor material, and is lower than the value of bulk-size material. This reduction in Seebeck coefficient of TiO 2 thin film is likely due to the low dimensional effect and the difference of carrier concentration.
