Vertical Transport in InAs/GaSb Superlattice at Low Temperatures

Vertical Transport in InAs/GaSb Superlattice at Low Temperatures We report on the vertical electron mobility versus temperature by applying the interface roughness scattering and the ionized impurity scattering in InAs/GaSb superlattices. Using the Finite Difference K.P method, we calculate the band structure of InAs/Gasb superlattices and then study the transport properties of these systems. The effects of several structural parameters such as layer thicknesses, interface roughness height, correlation length, and ion density are investigated for the vertical electron transport. Theoretical modeling results show that these two scattering mechanisms are important at low temperatures, and also in thin layer systems. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Low Temperature Physics Springer Journals

Abstract

We report on the vertical electron mobility versus temperature by applying the interface roughness scattering and the ionized impurity scattering in InAs/GaSb superlattices. Using the Finite Difference K.P method, we calculate the band structure of InAs/Gasb superlattices and then study the transport properties of these systems. The effects of several structural parameters such as layer thicknesses, interface roughness height, correlation length, and ion density are investigated for the vertical electron transport. Theoretical modeling results show that these two scattering mechanisms are important at low temperatures, and also in thin layer systems.
