Abstract
In-situ dynamic observations of surface phenomena using scanning tunnelingmicroscopy (STM) are performed.One of the example is as for the homoepitaxyand reconstructions on the heating Si (111) substrate.The growths ofthe 7×7 reconstruction and the 5×2 reconstruction due to gold deposition areobserved in the atomic scale.
The other observation is for the surface modification in the atomic scale onthe molybdenum-disulfide (MoS2). The individual atom on the surface is subtractedby the atomic manipulation using field evaporation phenomenon.
