“…The lattice constant of Ga 1-x In x Sb can also be adjusted by the In ratio (x), with a maximum adjustment range from 6.0959 Å (GaSb) to 6.4794 Å (InSb) [3]. And the band gap can be increased from 0.18 eV (InSb) to 0.725 eV (GaSb) [4,5], and the cutoff wavelength can be adjusted from 1.7 μm (GaSb) to 7.3 μm (InSb) [6]. Therefore, GaInSb crystals can be more widely used in epitaxial substrate materials [7], quantum well lasers [8], high electron mobility transistors [9], thermoelectric materials [10,11], as well as infrared (IR) and near-infrared (NIR) devices [12][13][14][15] and other fields.…”
