Determination of the Band-Gap of a Semiconductor ...
www.ijsr.netthe figure of merit, thermal conductivity, electrical conductivity and Seebeck coefficient. It is observed that the electric conductivity depends upon the energy Band Gap of the thermoelectric material. As soon as the Band Gap of the thermoelectric material reduces, it automatically increases the thermoelectric performance.
Chapter 9 THE MATERIALS SELECTION PROCESS
faculty1.aucegypt.edu• Lower thermal expansion coefficient reduces thermal stresse. • Lower thermal conductivity reduces heat losses. • The cost of material and processing will be used as a modifier to the material performance index. Materials and Process Selection for Engineering Design: Mahmoud Farag 22
Failure Mechanisms of Insulated Gate Bipolar Transistors ...
www.nrel.gov• The developed thermal stack model does not represent the actual thermal resistance network due to unknown spreading resistance, dissipation through the encapsulant and bond wires, and changing conductivity through the growing intermetallic.
