Tunable linear polarization of interface excitons at lateral heterojunctions
M. V. Durnev, D. S. Smirnov
We develop a theory of polarized photoluminescence of interface excitons localized at lateral heterojunctions between transition metal dichalcogenide monolayers. We show that the c…
Electric and spin-valley currents induced by structured light in 2D Dirac materials
A. A. Gunyaga, M. V. Durnev, S. A. Tarasenko
Structured optical fields can be used for the injection and control of charge and spin-valley currents. Here, we present a systematical study of these phenomena for interband absor…
Second harmonic generation due to spatial structure of radiation beam
A. A. Gunyaga, M. V. Durnev, S. A. Tarasenko
We show that spatially structured radiation generates second harmonic in a two-dimensional system even if the system is homogeneous and isotropic. The effect originates from non-lo…
Intervalley mixing of interface excitons at lateral heterojunctions
M. V. Durnev, D. S. Smirnov
$\require{mediawiki-texvc}$ We demonstrate that the low symmetry of armchair lateral heterojunction between transition metal dichalcogenide monolayers allows for the mixing of $\ma…
Photocurrents induced by structured light
A. A. Gunyaga, M. V. Durnev, S. A. Tarasenko
Advances in manipulating the structure of optical beams enable the study of interaction between structured light and low-dimensional semiconductor systems. We explore the photocurr…
