The structure of the Guinier–Preston (GP) zones precipitated in the Al–Si matrix composites after natural aging is investigated. The results show that, after natural aging, spherical GP zones with a diamond crystal structure form in the supersaturated α-Al matrix produced by high pressure solidification. The lattice parameter of the GP zones is 1.62nm and their structure consists of Si 3 atomic...
Thick GaN films with high quality have been grown on (0001) sapphire substrate in a home-made vertical HVPE reactor. Micron-size hexagonal pits with inverted pyramid shape appear on the film surface, which have six triangular {10–11} facets. These {10–11} facets show strong luminescence emission and are characteristic of doped n-type materials. Broad red emission is suppressed in {10–11} facets and...
