We investigate the electromechanical fields and transition energies of strained wurtzite InGaN quantum dot nanostructures. Electromechanical fields induced by lattice mismatches in heterostructures, both in and around quantum dots, are analyzed by using fully‐coupled electromechanical equations. The 4×4 Hamiltonian for the wurtzite structure is modified by incorporating the effects of electromechanical...
In this study, we investigate the influences of different composition distributions on the electronic structures of truncated cone‐shaped InGaN quantum dots (QDs). A varying parameter, $\alpha$, is defined as ${{w_1 } \mathord{\left/ {\vphantom {{w_1 } {w_2 }}} \right. \kern-\nulldelimiterspace} {w_2 }}$, in which w1 and w2 are the top and base diameter of QD, respectively. This factor is set to study...
