The Structure of GaSb Digitally Doped with Mn
G. I. Boishin, J. M. Sullivan, L. J. Whitman
Cross sectional scanning tunneling microscopy (XSTM) and density functional theory have been used to characterize the structure of GaSb digitally doped with Mn. The Mn dopants are…
Spin Polarization and Electonic Structure of Room-Curie Ferromagnetic Mn5Ge3 Epilayers
R. P. Panguluri, Changgan Zeng, H. H. Weitering +3
Germanium-based alloys hold great promise for future spintronics applications, due to their potential for integration with conventional Si-based electronics. Mn5Ge3 exhibits strong…
Cross-sectional STM of Mn-doped GaAs: theory and experiment
J. M. Sullivan, G. I. Boishin, L. J. Whitman +3
We report first-principles calculations of the energetics and simulated scanning tunneling microscopy (STM) images for Mn dopants near the GaAs (110) surface, and compare the resul…
Theory of dopants and defects in Co-doped TiO2 anatase
James M. Sullivan, Steven C. Erwin
We report first-principles microscopic calculations of the formation energy, electrical activity, and magnetic moment of Co dopants and a variety of native defects in TiO2 anatase.…
First-principles study of band offsets in ferromagnetic semiconductor heterojunctions
J. M. Sullivan, S. C. Erwin
We report valence and conduction band alignments and offsets for heterojunctions between CdCr2Se4, an n-type ferromagnetic semiconductor, and the non-magnetic materials Si and GaAs…
