Abstract
Dysprosium disilicide can form nanowires and three dimensional (3D) islands on the Si(001) surface. The nanowire density and width are metal coverage dependent. Various superstructures are observed on the nanowires. The Si substrate is also reconstructed in either 2×4 or 2×7 superstructures. The nanowires have a minimum height of about 0.5 nm with respect to the Si surface; and the heights of the additional layers growing atop nanowires are quantized, consistent with the hexagonal AlB 2 type silicide structure. Longer annealing time and higher coverage promote 3D island growth.This publication has 48 references indexed in Scilit:
