Paper Abstract

An attempt is made to study the heat capacity in 1uantum dots ( QDs) of nonlinear optical materials, taking n-LdGeAs2 as an example which also finds extensive applications in light emitting diodes. have for rnul ate d the he at c apac i ty in the QDs o f the s al d mater Ial by deducing a new dispersion law, within the framework of k.p. formalism Considering all types of anisotropies in the energy para- ieters. It is found, that the heat capacity increases with increa sing carrier density and decreases with increasing film thickness in an oscillatory manna' for both the eases respectively. The well known special eases have been derived from our generalized formula- tions under certain special conditions. The theoretical ex'essions are in agreement with the experimental observations as reported elsewhere.
