Possible Exotic Phases in the One-Dimensional Extended Hubbard Model
R. Torsten Clay, Anders W. Sandvik, David K. Campbell
We investigate numerically the ground state phase diagram of the one-dimensional extended Hubbard model, including an on--site interaction U and a nearest--neighbor interaction V.…
Dynamical Instabilities and Deterministic Chaos in Ballistic Electron Motion in Semiconductor Superlattices
Kirill N. Alekseev, Gennady P. Berman, David K. Campbell
We consider the motion of ballistic electrons within a superlattice miniband under the influence of an alternating electric field. We show that the interaction of electrons with th…
On Properties of Boundaries and Electron Conductivity in Mesoscopic Polycrystalline Silicon Films for Memory Devices
G. P. Berman, G. D. Doolen, R. Mainieri +4
We present the results of molecular dynamics modeling on the structural properties of grain boundaries (GB) in thin polycrystalline films. The transition from crystalline boundarie…
