This laboratory focuses its research on elucidating the correlation of structures and electronic interactions at nanoscale, and the evolution dynamics of surface/interface morphology. Such studies are conducted in both real and momentum space by employing ultrahigh vacuum variable temperature scanning probe microscopy and spot-profile analysis low energy electron diffraction.Additionally, the laboratory is equipped with a mini molecular beam epitaxy system that allows controlled growth of a series of heterostructures.Specific areas under investigation at present include (1) diffusion, coarsening, and reshaping of nanoclusters. (2) adsorption structure of radicals on metal surfaces and the associated electronic screening. (3) morphological instability of strained superlattice and its application in optoelectronics.
