This work presents both the parametrization procedure of a self-consistent charge density functional based tight-binding scheme (SCC-DFTB) for hafnium oxide and the structural as well as the electronic results of the simulations of amorphous hafnium

A multiple scale model approach is presented in order to investigate Al2O3 thin film growth in the framework of an existing Ion Beam Sputtering (IBS) coating process. Therefore, several simulation techniques are combined via optimized interfaces for

Simulation of the coating process is a very promising approach for the understanding of thin film formation. Nevertheless, this complex matter cannot be covered by a single simulation technique. To consider all mechanisms and processes influencing th

The electronic and optical properties of TiO2 atomic structures representing simulated thin films have been investigated using density functional theory. Suitable model parameters and system sizes have been identified in advance by validation of the

We simulate electronic and optical properties of TiO2 structures representing films with different densities. We calculate dependencies of bandgap and refractive index on film density. The observed dependencies are consistent with experimental data.

In order to determine the current status of thin film laser resistance within the private, academic, and government sectors, a damage competition was started at the 2008 Boulder Damage Symposium. This damage competition allows a direct comparison of
