Thermal Re-emission Model | | Amit K. Chattopadhyay

1 Mar 2001 | | Subject: | Statistical Mechanics | cond-mat.stat-mech | | Abstract: | Starting from a continuum description, we study the non-equilibrium roughening of a thermal re-emission model for etching in one and two spatial dimensions. Using standard analytical techniques, we map our problem to a generalized version of an earlier non-local KPZ (Kardar-Parisi-Zhang) model. In 2+1 dimensions, the values of the roughness and the dynamic exponents calculated from our theory go like $ alpha approx z approx 1 $ and in 1+1 dimensions, the exponents resemble the KPZ values for low vapor pressure, supporting experimental results. Interestingly, Galilean invariance is maintained althrough. | | Source: | arXiv, cond-mat/0103019 | | Services: | Forum | Review | PDF | Favorites | |
