(2012) Effects of Au catalyst on GaAs (111)B surface during annealing. In: 2012 Conference on Optoelectronic and Microelectronic Materials and Devices (COMMAD 2012), 12-14 Dec 2012, Melbourne, Australia.


To understand the growth mechanism and the effect of catalysts in growing III-V epitaxial nanowires, GaAs (111)B substrates with Au thin films were annealed in a molecular beam epitaxy (MBE) system. Scanning/transmission electron microscopy (SEM/TEM) investigations indicate that, during annealing, the Au catalysts were formed and affect significantly the surface morphology of the GaAs substrates.
