Effect of strain on surface diffusion in semiconductor heteroepitaxy
Evgeni Penev, Peter Kratzer, Matthias Scheffler
We present a first-principles analysis of the strain renormalization of the cation diffusivity on the GaAs(001) surface. For the example of In/GaAs(001)-c(4x4) it is shown that the…
First-principles studies of kinetics in epitaxial growth of III-V semiconductors
P. Kratzer, E. Penev, M. Scheffler
We demonstrate how first-principles calculations using density-functional theory (DFT) can be applied to gain insight into the molecular processes that rule the physics of material…
The role of electronic correlation in the Si(100) reconstruction: a quantum Monte Carlo study
Sorcha B. Healy, Claudia Filippi, P. Kratzer +2
Recent low-temperature scanning tunneling experiments have challenged the generally accepted picture of buckled silicon dimers as the ground state reconstruction of the Si(100) sur…
