Characterization of band offsets in Al${}_x$In${}_{1-x}$As${}_y$Sb${}_{1-y}$ alloys with varying Al composition

Jiyuan Zheng, Andrew H. Jones, Yaohua Tan +7

The unprecedented wide bandgap tunability (~1 eV) of Al${}_x$In${}_{1-x}$As${}_y$Sb${}_{1-y}$ latticed-matched to GaSb enables the fabrication of photodetectors over a wide range from near…
