The value of seebeck coefficient can be
WebThe Seebeck coefficient (also known as thermopower, thermoelectric power, and thermoelectric sensitivity) of a material is a measure of the magnitude of an induced thermoelectric voltage in response to a temperature difference across that material, as induced by the Seebeck effect. The SI unit of the Seebeck coefficient is volts per kelvin … WebThe films deposited on silica showed the highest values of Seebeck coefficient (S) and power factor (PF) in comparison with the films on Al 2 O 3 with the same content of SnO 2. The AZO film on silica with x = 2 showed the best performance, with σ = 385.0 S/cm, S = –74.17 mV/K, and PF = 211.8 μW/m·K 2 at the maximum operating temperature ...
