Sommerfeld enhancement factor in two-dimensional Dirac materials
N. V. Leppenen, L. E. Golub, E. L. Ivchenko
In this work the above-band gap absorption spectrum in two-dimensional Dirac materials is calculated with account for the interaction between the photocarriers. Both the screened R…

Nonlinear Absorption and Photocurrent in Weyl Semimetals
N. V. Leppenen, E. L. Ivchenko, L. E. Golub
Theory of light absorption and circular photocurrent in Weyl semimetals is developed for arbitrary large light intensities with account for both elastic and inelastic relaxation pr…

Circular photocurrent in Weyl semimetals with mirror symmetry
N. V. Leppenen, E. L. Ivchenko, L. E. Golub
We have studied theoretically the Weyl semimetals the point symmetry group of which has reflection planes and which contain equivalent valleys with opposite chiralities. These incl…
