곡률제한 모델과 잡음이 보존되는 높이차 제한 모델의 관계 연구

초록

We study the relation between the restricted curvature (RC) model and the conserved noise restricted solid on solid (CNRSOS) model. The surface width W of the RC model shows a roughness exponent rc ˘ = 1:5, a growth exponent rc ˘ = 0:375, and a dynamic exponent zrc ˇ 4 in one substrate dimension. The surface width W of the CNRSOS model shows a roughness exponent cn ˘ = 0:49, a growth exponent cn ˘ = 0:12, and a dynamic exponent zcn ˇ 4. The height di erence of the RC model can be interpreted as the height of the CNRSOS model. Therefore, there are some relations exist between the exponents for the RC model and the CNRSOS model: zrc = zcn, rc-1= cn, and rc- 1 zrc = cn.
