Periodic density functional calculations have been performed to study a mechanism of passivation of Mg-doped GaN by hydrogen. Optimizing different initial positions of hydrogen we found some favorable positions for the hydrogen atoms within the unit

The perpendicular forces acting on Pt adatoms from Pt(100) surfaces are presented using the embedded-atom method. The force maps are classified into four force regions. When the adatom is very close to the surface the force is repulsive (region 1). T

Crystal Structure and Dynamics of 12-Heteropoly Compounds as Investigated by Molecular Dynamics

Autor: Rajappan Vetrivel, Akira Miyamoto, Kazuya Tsujimichi, Momoji Kubo

Publikováno v: Journal of Catalysis. 157:569-575

The structure and dynamics of various atoms of the most common primary structure in heteropoly compounds, namely the Keggin structure were analyzed by molecular dynamics (MD). The atoms in the primary structure were found to remain rigid at 300 K. Th

Publikováno v: Japanese Journal of Applied Physics. 34:L789

Variations of atomic force microscopy (AFM) images as tip-sample distance is varied were examined using a newly developed AFM simulation code ACCESS (AFM simulation Code for Calculating and Evaluating Surface structures) with a Morse-type pairwise po
