Here in, we report on the fabrication of a flexible ultraviolet photodetector composed of two dimensional (2D) ZnO nanosheets (NSs) and one dimensional (1D) GaN nanorods (NRs). ZnO NSs were grown on the surface of GaN NRs to form 2D/1D heterojunction

We investigated the magnetic properties of as-sputtered FeTaN films as a function of deposition temperature and composition. At the deposition temperature higher than 200/spl deg/C, both soft magnetism and magnetic moments can be fully achieved. Whil
