Conduction in non-crystalline materials: III. Localized states in a pseudogap and near extremities of conduction and valence bands

NF Mott - Philosophical Magazine, 1969 - Taylor & Francis
If the distance between atoms in a crystalline lattice is increased, an energy gap appears,
which in a divalent material will separate occupied from unoccupied states of an electron. In …

The metallicity of thin films and overlayers

PA Dowben - Surface Science Reports, 2000 - Elsevier
Thin-film materials, normally considered metals, can exhibit behavior that is very
nonmetallic. There is an increasing body of experimental information that this phenomenon …

Electronic shell structure of group-IIIA metal atomic clusters

KE Schriver, JL Persson, EC Honea, RL Whetten - Physical review letters, 1990 - APS
Ionization potentials of Al n and In n clusters (n< 80) in supercooled beams have been
measured by photoionization spectroscopy. The abrupt leveling near n= 5 of the initial linear …

Size dependence of the gradual transition to metallic properties in isolated mercury clusters

K Rademann, B Kaiser, U Even, F Hensel - Physical review letters, 1987 - APS
Single-photon ionization thresholds are reported for mercury clusters with up to 70 atoms
prepared in a supersonic beam. The size dependence of the ionization potentials provides …

Excitonic insulator phase in

B Bucher, P Steiner, P Wachter - Physical review letters, 1991 - APS
We measured the Hall constant, resistivity, and magnetoresistance of the narrow-band-gap
semiconductor TmSe 0.45 Te 0.55 at pressures up to 17 kbar and down to 4 K. As the band …

Ab initio simulation of the metal/nonmetal transition in expanded fluid mercury

G Kresse, J Hafner - Physical Review B, 1997 - APS
We present an investigation of the variation of the structural and electronic properties of
liquid mercury for states along the liquid-vapor coexistence line, spanning the range from …

Gaseous metals

AA Likal'ter - Soviet Physics Uspekhi, 1992 - iopscience.iop.org
The physics of gaseous metals in the vicinity of the critical point is analyzed. A theory is
presented for mixed states of valence electrons in percolation clusters of overlapping atoms …

A theory of percolation in liquids

T DeSimone, S Demoulini, RM Stratt - The Journal of chemical physics, 1986 - pubs.aip.org
Problems involving percolation in liquids (ie, involving connectivity of some sort) range from
the metal–insulator transition in liquid metals to the properties of supercooled water. A …

Pressure-driven semiconductor-metal transition in intermediate-valence and the concept of an excitonic insulator

J Neuenschwander, P Wachter - Physical Review B, 1990 - APS
This work studies the pressure-induced semiconductor-to-metal transition (SMT) in the
TmSe-TmTe alloy system. This SMT is accompanied by a valence instability of the Tm ions …

Structural studies of expanded fluid mercury up to the liquid-vapor critical region

K Tamura, S Hosokawa - Physical Review B, 1998 - APS
The energy-dispersive x-ray-diffraction measurements for expanded fluid Hg were carried
out in the density region from 13.55 to 6.6 g cm− 3 including the metal-nonmetal (M− NM) …
