摘要：
The initial growth stage of self-induced GaN nanowires (NWs) on an AlN(0001)/Si(111) substrate is studied theoretically. Calculations are carried out within the model of Stranski-Krastanov quantum dot formation. The surface density of GaN islands is calculated, the formation of which precedes NW formation. GaN NW density is found as a function of gallium flux and deposition time for the case of molecular beam epitaxy growth.
