semiconductor-to-metal transitionIn this study the nature of transition to metallic regime in trans-polyacetylene (trans-PA) is investigated. Based on Su-Schrieffer-Heeger (SSH) model and the use of Continued - Fraction Representation (CFR) as well as Lanczos algorithm procedure, we studied the ...
metal-insulator transitionorganic light emitting diodesTemperature dependent Hall measurements revealed that ionized impurity scattering was the dominant mechanism in sputter deposited, degenerate, aluminum doped zinc oxide (AZO) films up to ~530nm thickness, and a semiconductor to metal transition was ...
Phase transitionIn this study, we report the phase transitions and semiconductor-to-metal (S-M) transition of hafnium selenide (HfSe2) under high pressure through experiments and theoretical calculations. The starting hexagonal structure transforms to an intermediate phase and I4/mmm structure above ...
We report by means of ab initio density functional theory based calculations that the semiconducting energy gap of bilayer transition metal dichalcogenides (TMDs) can be reduced by applying mechanical strains, tuning interlayer distance and applying an external electric field. Our results suggest that in...
Transport Properties and the Semiconductor-to-Metal Transition in V3O5 at High PressureV[3]O[5] is a representative of the homologous series of vanadiumoxides V[n]O[2n-1] known as the Magn茅 li phases. The physical andstructural properties of this oxide have widely been described in the...
The synthesis of two-dimensional (2D) transition metals has attracted growing attention for both fundamental and application-oriented investigations, such as 2D magnetism, nanoplasmonics and non-linear optics. However, the large-area synthesis of this class of materials in a single-layer form poses ...
Group III dopants in ZnO nanowires are predicted to tend to segregate to the surface and induce a metallic transition at high doping concentrations due to the delocalization of donor electron wave functions.doi:10.1039/c3ra43858aMaojie* Xu
Hybrid functional density functional theory calculations of the oxygen vacancy (VO) in monoclinic bulk WO(3) provide a coherent rationalization for the strong dependence of WO(3-x) electronic properties on the VO concentration and of the semiconductor-to-metal transition, a phenomenon intimately conne...

Dynamic structures of liquid TeSeand TeSewere investigated by inelastic neutron scattering experiments in the semiconductor-to-metal transition range. The bond-stretching modes for the both liquid mixtures were found to clearly soften when the transition occurs. We discuss the change of static and ...
