A simple qualitative model, named Qi model which is further extended to Bond energy model has been expressed in terms of melting temperature to explain the shape and size effect on Debye temperature ( ) and Einstein temperature ( ) of nanomaterials. It is known that properties of materials drastically change with size reduction to nanorange and increase in the number of surface atoms with respect to volume of the nanostructure. It is found that Debye temperature and Einstein temperature get reduced in free standing nanostructures as their size is reduced. The variation in these physical properties viz. Debye temperature ( ) and Einstein temperature ( ) is calculated for spherical nanoparticles, thin film, and nanowires for considered nanomaterials. The computed results are compared with the available experimental results and it is found that there is a good agreement between them. The results obtained for the bulk materials are also depicted in the graphs to judge the stability of this work.

Keywords: Debye temperature, Einstein temperature, size, shape, nanowire.
