Effect of post-growth annealing on the optical properties of InAs/GaAs quantum dots: A tight-binding study
R. Santoprete, P. Kratzer, M. Scheffler +2
We present an atomistic study of the strain field, the one-particle electronic spectrum and the oscillator strength of the fundamental optical transition in chemically disordered I…

Jahn-Teller stabilization of a "polar" metal oxide surface: Fe3O4(001)
R. Pentcheva, F. Wendler, H. L. Meyerheim +3
Using ab initio thermodynamics we compile a phase diagram for the surface of Fe3O4(001) as a function of temperature and oxygen pressures. A hitherto ignored polar termination with…
