Model for the magnetoresistance and Hall coefficient of inhomogeneous graphene [PDF]

open access: yes, 2008
We show that when bulk graphene breaks into n-type and p-type puddles, the in-plane resistivity becomes strongly field dependent in the presence of a perpendicular magnetic field, even if homoge- neous graphene has a field-independent resistivity.

Normal state resistivity of Ba$_{1-x}$K$_x$Fe$_2$As$_2$: evidence for multiband strong-coupling behavior [PDF]

open access: yes, 2011
We present theoretical analysis of the normal state resistivity in multiband superconductors in the framework of Eliashberg theory. The results are compared with measurements of the temperature dependence of normal state resistivity of high-purity Ba$_{0.

Linear-$T$ resistivity from low to high temperature: axion-dilaton theories

open access: yes, 2020
The linear-$T$ resistivity is one of the hallmarks of various strange metals regardless of their microscopic details. Towards understanding this universal property, the holographic method or gauge/gravity duality has made much progress.

BLOCH WAVE – ZRP SCATTERING AS A KEY ELEMENT OF SOLID STATE PHYSICS COMPUTATION: 1D EXAMPLE

open access: yesTASK Quarterly, 2016
This paper presents calculation of the electron-impurity scattering coefficient of Bloch waves for one dimensional Dirac comb potential. The impurity is also modeled as delta function pseudopotential that allows explicit solution of the Schrodinger ...

Modelling of changes in the resistivity of semi-insulating materials [PDF]

open access: yesMetrology and Measurement Systems, 2021
Electrical properties of semiconductor materials depend on their defect structure. Point defects, impurities or admixture contained in a semiconductor material, strongly affect its properties and determine the performance parameters of devices made on ...
