Self-assembly of coherent quantum-dots of ZnO semiconductor
Abstract
We studied growth dynamics of fabricated ZnO quantum-dot on the lattice mismatched substrate. The ZnO quantum dots grown by RF-magnetron sputtering method were formed on bare substrate surface for the Volmer-Weber growth or on the well-aligned wetted surface for the Stranski-Krastanov growth. Discrete self assembled ZnO quantum dot were undergone Ostwald ripening and coalescences processes above certain critical size. Therefore, discrete ZnO quantum dots changed to the continuous planer layer. We measured the epitaxy c-axis orientation on the surface normal direction of ZnO quantum dots by the synchrotron x-ray scattering method.
