Interface dipoles of organic molecules on Ag(111) in hybrid density-functional theory
Oliver T. Hofmann, Viktor Atalla, Nikolaj Moll +2
We investigate the molecular acceptors 3,4,9,10-perylene-tetracarboxylic acid dianhydride (PTCDA), 2,3,5,6-tetra uoro-7,7,8,8-tetracyanoquinodimethane (F4TCNQ), and 4,5,9,10-pyrene…
Formation and stability of self-assembled coherent islands in highly mismatched heteroepitaxy
L. G. Wang, P. Kratzer, M. Scheffler +1
We study the energetics of island formation in Stranski-Krastanow growth within a parameter-free approach. It is shown that an optimum island size exists for a given coverage and i…
The influence of surface stress on the equilibrium shape of strained quantum dots
N. Moll, M. Scheffler, E. Pehlke
The equilibrium shapes of InAs quantum dots (i.e., dislocation-free, strained islands with sizes >= 10,000 atoms) grown on a GaAs (001) substrate are studied using a hybrid approac…
