Complete composition tunability of InGaN nanowires using a combinatorial approach

Tevye Kuykendall , Philipp Ulrich , Shaul Aloni & Peidong Yang

The III nitrides have been intensely studied in recent years because of their huge potential for everything from high-efficiency solid-state lighting and photovoltaics to high-power and temperature electronics. In particular, the InGaN ternary alloy is of interest for solid-state lighting and photovoltaics because of the ability to tune the direct bandgap of this material from the near-ultraviolet to the near-infrared region.
