Abstract: AlxGa1-xN III-V Ternary semiconductor is essential being an x of the constituent within the semiconductor will have significant alterations in calculating Physical Property like Band Energy Gap. These Ternary Compounds could be produced from binary compounds AlN and GaN by changing half from the atoms in a single sub lattice by lower valence atoms, another half by greater valence atoms and looking after average quantity of valence electrons per atom. The subscript X refers back to the alloy content or power of the fabric, which describes proportion from the material added and changed by alloy material. This paper signifies the AlxIn1-xSb III-V Ternary Semiconductor Band Energy Gap values

Key phrases: Band Energy Gap, Composition, Electro Negativity, Molecular weight, density, optical polarizability.
