Abstract
ZnO grown by plasma enhanced molecular beam epitaxy on (0001) sapphire substrates was found to consist of a 300 nm epitaxial layer with quantum sized pyramids on the surface. Room temperature stimulated emission was observed from these samples with a threshold intensity of 300 kWcm-2. Stimulated emission was observed at 500 K and T0 is found to be around 90 K in the range 300 K to 500 K.
