Effect of uniaxial stress on the longitudinal magnetophonon oscillations inn−InSb

Abstract

The stress dependence of the longitudinal magnetophonon effect was investigated at 77 K in $n$-type InSb. Uniaxial compressive stresses were applied along the [110], [111], and [211] crystallographic directions. The [110] and [111] data, along with the previously measured stress dependence of the transverse magnetophonon effect, enabled values of the hydrostatic ($a+C_1$) and the two shear ($b$ and $d$) deformation potentials to be unambiguously determined.
