Ground-state structure of the hydrogen double vacancy on Pd(111)
Sungho Kim, Seong-Gon Kim, S. C. Erwin
We determine the ground-state structure of a double vacancy in a hydrogen monolayer on the Pd(111) surface. We represent the double vacancy as a triple vacancy containing one addit…
Structure of AlSb(001) and GaSb(001) Surfaces Under Extreme Sb-rich Conditions
Jeffery Houze, Sungho Kim, Seong-Gon Kim +2
We use density-functional theory to study the structure of AlSb(001) and GaSb(001) surfaces. Based on a variety of reconstruction models, we construct surface stability diagrams fo…
Thermodynamics of carrier-mediated magnetism in semiconductors
A. G. Petukhov, Igor Zutic, Steven C. Erwin
We propose a model of carrier-mediated ferromagnetism in semiconductors that accounts for the temperature dependence of the carriers. The model permits analysis of the thermodynami…
Observing Spin Polarization of Individual Magnetic Adatoms
Y. Yayon, V. W. Brar, L. Senapati +2
We have used spin-polarized scanning tunneling spectroscopy to observe the spin-polarization state of individual Fe and Cr atoms adsorbed onto Co nanoislands. Both of these magneti…
