Abstract
A simple unified model is used to study the variation in Debye temperature in monometallic and bimetallic nanoalloys. In the present study, a systematic investigation of variation in Debye temperature is done to analyze the impact of size, shape, composition and dimension in monometallic and bimetallic nanoalloys. It is found that Debye temperature in monometallic and bimetallic nanoalloys decreases with decrease in size of nanoalloy. Moreover, for nanoalloys of same size and composition, the Debye temperature varies with dimension too. Debye temperature of nanofilms is found more than that of nanowires and nanoparticles. Debye temperature is also found to vary with shape of the nanoalloy due to change in surface area to volume ratio with shape. The predicted model results are found in good agreement with the available experimental results which justifies the suitability of the present model.
