Quaternary Alloy Semiconductor Nanobelts with Bandgap Spanning the Entire Visible Spectrum

摘要

The ability to engineer and control compositions of semiconductor alloys is one of the ultimate goals of semiconductor material science and engineering. Nanomaterials such as nanowires and nanobelts offer an unprecedented opportunity for alloy composition control in a wide range, unavailable with traditional epitaxial film materials, and have attracted a great deal of attention recently, with special focus on achieving a wide range of bandgaps through various ternary alloys.
