Computational Search for Two-Dimensional MX2 Semiconductors with Possible High Electron Mobility at Room Temperature
Neither of the two typical two-dimensional materials, graphene and single layer MoS 2 , are good enough for developing semiconductor logical devices. We calculated the electron mobility of 14 two-dimensional semiconductors with composition of MX 2 , where M (=Mo, W, Sn, Hf, Zr and Pt) are transition metals, and Xs are S, Se and Te. We approximated the electron phonon scattering matrix by deform...
متن کاملHigh temperature superconductivity from the two-dimensional semiconductors without magnetism
We examine the possibility of high temperature superconductivity from two-dimensional semiconductor without antiferromagnetic fluctuations. The weak coupling BCS theory is applied, especially where the Fermi level is near the bottom of the conduction band. Due to screening, the attractive interaction is local in k-space. The density of states(DOS) does not have a peak near the bottom of the ban...
متن کاملRoom-temperature exciton-polaritons with two-dimensional WS2
Two-dimensional transition metal dichalcogenides exhibit strong optical transitions with significant potential for optoelectronic devices. In particular they are suited for cavity quantum electrodynamics in which strong coupling leads to polariton formation as a root to realisation of inversionless lasing, polariton condensation and superfluidity. Demonstrations of such strongly correlated phen...
متن کاملIs room-temperature superconductivity with phonons possible?
By recognizing the vital importance of two-hole Cooper pairs (CPs) in addition to the usual two-electron ones in a strongly-interacting many-electron system, the concept of CPs was re-examined with striking conclusions: namely, they are gapped and linearly-dispersive resonances with a finite lifetime—but provided the ideal-gas Fermi sea is replaced by a BCS-correlated unperturbed ground-state “...
متن کاملNanotubes are High Mobility Semiconductors
The electron transport properties of a very long (20 micron) CVD-grown nanotube are reported. In this device the transport is dominated by intrinsic scattering processes at room temperature. The room temperature hole mobility is 20,000 cm/Vs, exceeding that of technologically-relevant semiconductors. The mobility increases with decreasing temperature, and is estimated to be greater than 180,000...
