Microwave Sintering of High Thermal Conductivity Aln

In this study, a combustion synthesized AlN powder was sintered using microwave as heating source. The microwave was 2.45 GHz and the sintering process was carried out in a single-mode cavity. The sintering temperature was between 1800°C and 2000°C with a power ranging from 400 to 700W. The as-synthesized AlN was ground to under 2μm and yttria was used as sintering aid. The effects of the amoun...

Valence band mixing of cubic GaN/AlN quantum dots.

We study the spin purity of the hole ground state in nearly axially symmetric GaN/AlN quantum dots (QDs). To this end, we develop a six-band Burt-Foreman Hamiltonian describing the valence band structure of zinc blende nanostructures with cylindrical symmetry and calculate the effects of eccentricity variationally. We show that the aspect ratio is a key factor for spin purity. In typical QDs wi...
