Molecular beam epitaxial growth and optical properties of InAs1−xSbx in 8–12 μm wavelength range

Abstract
We have successfully grown InAs1−xSbx by molecular beam epitaxy over the complete compositional range of 0<x<1 on InAs substrates. The band gaps have been measured using optical absorption and cut‐off wavelengths as long as 12.5 μm have been obtained.
