英文摘要	The deformation potential and piezoelectric field in nitride GaN/AIN quantum dots (QDs) are investigated in the framework of effective mass approximation (EMA) and finite element method (FEM). The strained fields and piezoelectric characteristics are studied by using FEM for GaN/AIN QDs (GaN embedded in AIN) in the shape of truncated hexagonal pyramids. We presented the calculated results of the electronic states, wave functions, QD strain field distribution and piezoelectric effects in the QDs. Effects of spontaneous and piezoelectric polarization are taken into account in the calculation. The theoretical results are dependent on QD shapes and sizes. Some of them make the GaN/AIN QDs interesting candidates in optoelectronic applications.; Physics, Multidisciplinary; SCI(E); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 0; ARTICLE; 4; 956-959; 23
