Abstract
We report some results on the analysis of thermo-electromechanical effects in low dimensional semiconductor nanostructures (LDSNs). A coupled model of thermoelectroelasticity has been applied to the analysis of quantum dots and quantum wires. Finite element solutions have been obtained for different thermal loadings and their effects on the electromechanical properties in quantum dots and quantum wires are presented. Our model accounts for a practically important range of internal and external thermoelectromechanical loadings. Results are obtained for typical quantum dot and quantum wire systems with cylindrical geometry. The comparative analysis of thermoelectromechanical effects in quantum dots and quantum wires is also presented. It is observed that the electromechanical effects in LDSNs are noticeably influenced by thermal loadings. The influence is more significant in quantum dots as compared to that of quantum wires.
