Electronic structure of the Ge/Si(105) hetero-interface
Polina M. Sheverdyaeva, Conor Hogan, Anna Sgarlata +5
Thin Ge layers deposited on Si(105) form a stable single-domain film structure with large terraces and rebonded-step surface termination, thus realizing an extended and ordered Ge/…
Evolution of self-assembled InAs/Gas(001) quantum dots grown by growth-interrupted molecular beam epitaxy
A. Balzarotti
Self-assembled InAs quantum dots (QDs) grown on GaAs(001) surface by molecular beam epitaxy under continuous and growth-interruption modes exhibit two families of QDs, quasi-3D (Q3…
Experimental corroboration of the Mulheran-Blackman explanation of the scale invariance in thin film growth: the case of InAs quantum dots on GaAs(001)
M. Fanfoni, E. Placidi, F. Arciprete +3
Mulheran and Blackman have provided a simple and clear explanation of the scale invariance of the island size distribution at the early stage of film growth [Phil. Mag. Lett. 72, 5…
How kinetics drives the two- to three-dimensional transition in semiconductor strained heterostructures: the case of InAs/GaAs(001)
F. Arciprete, E. Placidi, V. Sessi +3
The two- to three-dimensional growth transition in the InAs/GaAs(001) heterostructure has been investigated by atomic force microscopy. The kinetics of the density of three dimensi…
W=0 pairing in Hubbard and related models of low-dimensional superconductors
Adalberto Balzarotti, Michele Cini, Enrico Perfetto +1
Lattice Hamiltonians with on-site interaction have W=0 solutions, that is, many-body {\em singlet} eigenstates without double occupation. In particular, W=0 pairs give a clue t…
Canonical Transformation of the Hubbard Model and W=0 Pairing: Comparison with Exact Diagonalization Results
Michele Cini, Adalberto Balzarotti, Raffaella Brunetti +2
We have recently developed a canonical transformation of the Hubbard and related models, valid for systems of arbitrary size and for the full plane; this is particularly suited to…
