Self-assembled formation and transformation of In/CdZnTe (110) nano-rings into camel-humps
G Cohen-Taguri, A Ruzin, I Goldfarb - Applied Physics Letters, 2012 - pubs.aip.org
We used in situ scanning tunneling microscopy to monitor in real time the formation of nano-
rings at the molecular beam epitaxially grown In/CdZnTe ( 110) surface, and Auger
electron spectroscopy to explore the corresponding compositional changes. In-diffusion of In
and segregation of Cd to the surface in course of annealing lead to a formation of elliptically
distorted nano-rings, elongated along the fast [1 10] diffusion direction. Exacerbated
diffusion anisotropy in the liquid state, at temperatures above the melting point of In, further …
