In less than a decade, the field of InGaN nanowires went from birth to maturity, with full characterization, clear industrial applications, and a shift in focus from figuring out how to make the material, to understanding how to make it cheaply and efficiently. The tunable band gap of InGaN gives the material a tremendous amount of power in both the generation and conversion of light, and quite often nanowires are the best form for the material. Such nanowires are particularly useful in the field of water splitting, though applications in the well-trod field of LEDs and the unknown territory of photovoltaic cells are also promising. With an increasing premium being put on efficiency and solar energy, it is likely demand for these uses will not die down– but there very well may be as of yet unknown uses for InGaN nanowires and their unique photoelectronic properties.
