Transmission Electron Microscopic Study of the Surface and Interface of Carbonized-Layer/Si(100)

Abstract
A heterojunction of carbonized-layer/Si(100) was studied by means of a transmission electron microscope (TEM). The surface layer was clarified to be well aligned to substrate Si(100) by a crosssectional TEM observation. Small misorientation was observed at the bottom of the carbonized layer. Either the surface or the interface of the overlayer had a rough structure with a thickness of a few nm. A plane-view observation revealed the existence of fine grains in the grown layer with a size of \lesssim10 nm, which rotated a little with respect to the substrate Si(100) and each other.
