Proof of universality of electrical conductivity at finite chemical potential
electrical conductivity finite chemical potential
2010/12/23
It was proposed in arXiv:1008.2944 that, for certain gauge theories with gravity duals, electrical conductivity at finite chemical potential is universal. Here we provide a general proof that, when m...
Quark mass dependence of the vacuum electric conductivity induced by the magnetic field in SU(2) lattice gluodynamics
the vacuum electric conductivity the magnetic field
2010/12/27
We study the electric conductivity of the vacuum of quenched SU(2) lattice gauge theory induced by the magnetic field B as a function of the bare quark mass m. The conductivity grows as the quark mas...
The influence of Ge content and annealing temperature on the d.c and a.c conductivity of GexSe1 - x thin films
a.c conductivity d.c conductivity thin GexSe1 - x film dielectric constant
2010/4/13
Various samples of GexSe1 - x system have been prepared for x = 0.05, 0.15& 0.25 in an evacuated quartz tube. Thin films of GexSe1 - x film have been prepared via a thermal evaporation method with 350...
The Temperature Dependence of Dark Conductivity in Hydrogenated Amorphous SiNx Films
A. Dark Conductivity B. Activation energy C. Pre-exponential factor D. Hydrogenated amorphous silicon nitride
2010/4/15
Thin film samples of hydrogenated amorphous silicon nitride with varying nitrogen content were prepared by conventional plasma deposition from a mixture of SiH4 and NH3 . The dark conductivity (sd) of...
