TI - Effect of QWR Shape on the Induced Elastic and Piezoelectric Fields T2 - Computer Modeling in Engineering \& Sciences PY - 2004 VL - 6 IS - 1 SN - 1526-1506 AB - It is of great importance to understand the factors that contribute to the strain and electrical distributions, which are induced by the misfit strain between a buried quantum wire (QWR) and its surrounding matrix. One of the important factors is the shape or geometry of cross section of the QWR. Utilizing a recent exact closed-form solution [Pan (2004)], we study the model system of QWRs with different shapes and calculate both the surface and internal elastic and piezoelectric fields induced by QWRs embedded in semiconductor GaAs substrates by properly setting the size and location of the QWRs. The effects of the QWR shape as well as the material orientation and free surface of the substrate on the elastic and piezoelectric fields are clearly demonstrated. Key conclusions are also drawn.
