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…
Engineering electron and hole tunneling with asymmetric InAs quantum dot molecules
A. S. Bracker, M. Scheibner, M. F. Doty +6
Most self-assembled quantum dot molecules are intrinsically asymmetric with inequivalent dots resulting from imperfect control of crystal growth. We have grown vertically-aligned p…
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…
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…
Frenkel-Kontorova Model of Vacancy-Line Interactions on Ga/Si(112): Formalism
S. C. Erwin, A. A. Baski, L. J. Whitman +1
We describe in greater detail the exactly solvable microscopic model we have developed for analyzing the strain-mediated interaction of vacancy lines in a pseudomorphic adsorbate s…
Structure and Stability of Si(114)-(2x1)
Steven C. Erwin, Alison A. Baski, Lloyd J. Whitman
We describe a recently discovered stable planar surface of silicon, Si(114). This high-index surface, oriented 19.5 degrees away from (001) toward (111), undergoes a 2x1 reconstruc…
