In this brief, room-temperature visible electroluminescence (EL) from aluminum nitride (AlN) thin films containing aluminum nanocrystals (nc-Al) prepared by a radio-frequency magnetron sputtering technique is reported. The EL shows a broad spectrum peaked at 565 nm (2.19 eV) when a negative gate vol...
