Diffusion - Limited Aggregation Processes with 3 - Particle Elementary Reactions

A diffusion-limited aggregation process, in which clusters coalesce by means of 3-particle reaction, A + A + A → A, is investigated. In one dimension we give a heuristic argument that predicts logarithmic corrections to the mean-field asymptotic behavior for the concentration of clusters of mass m at time t, C m (t) ∼ m −1/2 (log(t)/t) 3/4 , for 1 ≪ m ≪ t/ log(t). The total concentration of clu...

Elementary processes in chemical vapor deposition: quantum chemical approach

Chemical vapor deposition (CVD) is one of the key technologies for the epitaxial crystal growth of semiconductors. In order to obtain high-performance devices, atomically controlled thin films are required. Layer by layer growth consists of various processes, i.e ., the thermal decomposition of precursors, the adsorption of growing species, their surface migration, two-dimensional nucleation, t...

The Quantum Statistical Mechanical Theory of Transport Processes

A new derivation of the quantum Boltzmann transport equation for the Fermion system from the quantum time evolution equation for the wigner distribution function is presented. The method exhibits the origin of the time - irreversibility of the Boltzmann equation. In the present work, the spin dependent and indistinguishibility of particles are also considered.
