Bringing Down the Cost of III-V Epitaxy

Research output: Contribution to journalArticle


III-V semiconductors are the gold standard for many devices. They sit at the heart of lasers and LEDs, high-speed and high-power electronics, and space photovoltaics (PVs). Consider, for example, the latter: PVs made from III-Vs have demonstrated the highest energy-conversion efficiency and specific power for any material system, and can be very lightweight, thin and flexible, as well as incredibly stable - that's everything anyone would want from a solar cell. What III-Vs are not, however, is cheap - at least on a cost-per-area basis - due to a lack of driving force to make them so.
