Heat Generation in Spatially Confined Solids Through Electronic Light Scattering
Sergey Kharintsev, Elina Battalova
In this Letter, we study the optical heating of spatially dispersive solids due to electronic light scattering (ELS), a phenomenon driven by indirect optical transitions. In this p…
Off-Resonance Enhancement of the Refractive Index via Indirect Optical Transitions
E. I. Battalova, A. I. Minibaev, A. V. Petrov +1
At resonance, the optical response of a homogeneous medium to incident light is governed by temporal dispersion, which induces changes in the refractive index (RI). However, recent…
Electronic Raman scattering in silicon glass
Sergey S. Kharintsev, Elina I. Battalova, Aleksey I. Noskov +3
The nature of enhanced photoemission in disordered and amorphous solids is an intriguing open question. A point in case is light emission in silicon, which occurs when the material…
Photon momentum enabled light absorption in bulk silicon
Sergey S. Kharintsev, Aleksey I. Noskov, Elina I. Battalova +6
Photons do not carry sufficient momentum to induce indirect optical transitions in semiconducting materials such as silicon, necessitating the assistance of lattice phonons to cons…
Light-controlled multi-phase structuring of perovskite crystal enabled by thermoplasmonic metasurface
Sergey S. Kharintsev, Elina I. Battalova, Timur A. Mukhametzyanov +5
Halide perovskites belong to an important family of semiconducting materials with unique electronic properties that enable a myriad of applications, especially in photovoltaics and…
