Resistivity of non-Galilean invariant two dimensional Dirac system
V. M. Kovalev, M. V. Entin, Z. D. Kvon +4
We revisited the influence of electron-electron scattering on the resistivity of a two-dimensional system with linear spectrum. In conventional systems with parabolic spectrum, whe…

Interaction-controlled transport in a two-dimensional massless-massive Dirac system: Transition from degenerate to nondegenerate regimes
A. D. Levin, G. M. Gusev, F. G. G. Hernandez +4
The resistivity of two-dimensional (2D) metals generally exhibits insensitivity to electron-electron scattering. However, it's worth noting that Galilean invariance may not hold tr…

Electron-hole scattering-induced temperature behaviour of HgTe-based semimetal quantum well
A. V. Snegirev, V. M. Kovalev, M. V. Entin +3
The semimetal quantum well (QW) based on HgTe structures exhibiting unusual transport properties at low temperature is examined experimentally. It demonstrates either a linear or q…
