摘要: 用结构函数的方法建立了SiC粗糙表面的分形模型,用rms粗糙度Δ,分形维数D,以及相关长度L三个参量来刻画表面高度的自协方差函数,并提出了参数的计算方法.在此分形模型的基础上,能计算出SiC/SiO2界面对沟道电子的粗糙散射.
关键词: 分形, SiC, 界面粗糙散射, MOSFET
Abstract: A fractal model of coarse surface of SiC by using structure function is presented.Three parameters rms roughness Δ,fractal dimension D,and correlative length L are used to describe the covariance function of surface height.The method calculating these parameters is also given.With the present model,one can calculate the coarse dispersion of SiC/SiO2 fractal interface to channel electrons.
Key words: fractal, coarse interface dispersion, MOSFET, silicon carbide
