In the conduction band of III-V semiconductors having cubic zinc-blende structure there are local energetic minima at the Γ, X and L points of the Brillouin zone. The idea that electrons in the conduction band are scattered by phonons between these valleys first became important in theories of the Gunn effect[1,2]. In recent years the intervalley scattering process has been extensively investigated in III–V semiconductors [3] mainly because of two reasons: first, ultrafast optical spectroscopy became available for investigating scattering processes which take place on a femtosecond timescale. Secondly, the transport properties of high-speed electronic semiconductor devices[4] are influenced by intervalley scattering.
