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…
Metastability of NbN in the ordered vacancy NbO phase
E. C. Ethridge, S. C. Erwin, W. E. Pickett
A metastable phase of NbN with superconducting Tc=16.4 K was reported recently by Treece and collaborators. The reported structure of the thin film sample deviates from the rocksal…
Commensurate and modulated magnetic phases in orthorhombic A1C60
E. J. Mele, G. V. Krishna, S. C. Erwin
Competing magnetically ordered structures in polymerized orthorhombic A1C60 are studied. A mean-field theory for the equilibrium phases is developed using an Ising model and a clas…
Three-dimensional electronic instabilities in polymerized solid A1C60
S. C. Erwin, G. V. Krishna, E. J. Mele
The low-temperature structure of A1C60 (A=K, Rb) is an ordered array of polymerized C60 chains, with magnetic properties that suggest a non-metallic ground state. We study the para…
