Linear photogalvanic effect in surface states of topological insulators
N. V. Leppenen, L. E. Golub
Theory of the Linear photogalvanic effect is developed for direct optical transitions between surface states of three-dimensional topological insulators. The photocurrent governed…
Nonlinear optical absorption and photocurrents in topological insulators
N. V. Leppenen, L. E. Golub
Theory of optical absorption of linearly and circularly polarized light in surface and edge states in topological insulators is developed for a nonlinear in light intensity regime.…
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…
