【 摘 要 】

The structural properties of TlxGa1-xN have been examined by the use of interaction potential model (IPM). Interaction potential model (IPM) is made up of Coulomb interaction, three-body interaction, van der Waal interaction and short range overlap repulsive interactions. The structural properties namely phase transition, volume collapse for the present alloy have been computed via vegard's law. We have also investigated the elastic properties i.e. second order elastic constants, bulk modulus, shear modulus, Pugh ratio and anisotropy factor. These elastic properties are the first attempt for the present alloy.
