Abstract(in English) | We have examined the effect on a two-dimensional electron gas (2DEG) in AlGaN/GaN hetero structures by using the "micro-origami" method. In this study, lattice strain, bending deformation, and variations of piezoelectric charge as well as 2DEG density were analyzed for a basic cantilever of the bimetal structure. These simulations were performed by using the finite element method and the finite difference method. As a result, the 2DEG density at the Al_<0.2>Ga_<0.8>N/GaN hetero-interface was found to decrease approximately 37%. The result suggests that the 2DEG density is controllable in the micro-origami type of MEMS structures. |
