On the Nature of Metal–Semiconductor Phase Transition in Vanadium Dioxide

Physics of the Solid State, 2000
The method of coercive temperature distribution function is used to prove that the metal-semiconductor temperature-induced phase transition in vanadium dioxide manifests itself as a Mott electronic transition.

Metal-semiconductor transition in CuS-Cu1.8S mixed phase thin films

Vacuum, 2015
Abstract We report the semiconducting behavior at room temperature and a metal-semiconductor transition (MST) at lower temperature in copper sulfides (Cu x S) thin films. Cu x S thin films, deposited by direct magnetron sputtering technique, are found to be of CuS-Cu 1.8 S mixed phase by XRD. The deposited films exhibit low electrical resistivity

Time-resolved characteristics of phase conjugation in metal–semiconductor phase transition in VO2

Applied Physics Letters, 1999
The change in the reflection behavior of VO2 films for the 1.06 μm wavelength at the semiconductor–metal phase transition was investigated. The nonlinearity caused by photoinduced transition was used for phase conjugation of a pulsed Nd:YAG laser.

Reversible structural phase transitions in semiconductor and metal/semiconductor surfaces

Journal of Physics: Condensed Matter, 2002
We review our current understanding of the reversible phase transitions found in clean semiconductor and metal/semiconductor surfaces. The most important phase transitions are considered in detail, in particular those appearing in Si(001), Ge(001), Si(111), Ge(111), 3C-SiC(001), Pb and Sn on Si(111) and Ge(111), Au/Si(111) and Ag/Si(111).

Phase transitions of magnetic nanoclusters in metals and semiconductors

Physica A: Statistical Mechanics and its Applications, 2003
Abstract The interactions and phase transitions of magnetic nanoclusters embedded in nonmagnetic metals and semiconductors are investigated theoretically. As a consequence of the temperature dependence of the indirect interactions, it is shown that for semiconductors several ferromagnetic phase transitions are possible depending on the size of the ...

On metal-insulator electronic phase transitions in semiconductors

Semiconductors, 2006
Some aspects of the problem of metal-insulator electronic phase transitions in semiconductors, which were not adequately studied previously, are examined in this paper. The issues considered are the effect of the hybridization between the resonance quasi-bound impurity states and the band continuum states on the transition, the effect of the uniform ...

Plasmonic Probe of the Semiconductor to Metal Phase Transition in Vanadium Dioxide

Nano Letters, 2013
An array of 180 nm diameter gold nanoparticles (NPs) embedded in a thin vanadium dioxide film was used as a nanoscale probe of the thermochromic semiconductor-to-metal transition (SMT) in the VO2. The observed 30% reduction in plasmon dephasing time resulted from the interaction between the localized surface plasmon resonance of the NPs with the 1.4 eV

Semiconductor-metal phase transition in rare-earth semiconductors (samarium monochalcogenides)

Soviet Physics Uspekhi, 1978
A review is given of the theoretical and experimental data on the isostructural first-order semiconductor-metal phase transition in samarium monosulfides and Sm1-xLnx3+S solid solutions (Ln is a rare-earth metal). Phase transitions occurring under hydrostatic pressures and as a result of change in temperature are considered.
