Tunneling conductivity features of the new reconstructed phases on the GaN (0001) surface
PACS: 61.16.-d, 71.70.Gm
Abstract
Two new Au-induced reconstructed phases on the GaN (0001) surface have been found out and investigated by STM/STS method. Ring-like and c(2×12) surface nanostructures were observed on STM images. The commensurate c(2×12) structure (α-phase) according to our spectroscopic measurements demonstrates properties of 1D system whereas the incommensurate β-phase looks similar to disordered 2D system.
