Shift of a Γ- X junction due to hydrostatic pressure

Hydrostatic pressure causes a shift of a Γ- X junction in the direction opposite to the band-gap gradient. The shift is of the order of 1μ/kbar in the samples investigated. From the shift and the band-gap gradient, the intervalley pressure coefficient (∂/∂ P) ( E X– E Γ) is estimated to be — 9·0 -6...

Description
Summary:Hydrostatic pressure causes a shift of a Γ- X junction in the direction opposite to the band-gap gradient. The shift is of the order of 1μ/kbar in the samples investigated. From the shift and the band-gap gradient, the intervalley pressure coefficient (∂/∂ P) ( E X– E Γ) is estimated to be — 9·0 -6 eV/bar for the composition of Al x Ga 1- x As corresponding to the Γ- X crossover.
