Studies of Field -Induced Stress on Ultrathin Layers of Silicon Dioxide on a Silicon Substrate
We present here the results of an STM study of ultrathin silicon dioxide layers on a silicon substrate. We have found that under certain conditions, structures subjected to field-induced stress with the STM exhibit changes in their conductivity which we believe are evident in the images as the …

Optical Studies of Ordered Monomolecular Layers: Ab Initio Simulation and Experiment
… on the alignment effect of the surface-bound ultrathin layers, this thesis presents research of the investigation of anchoring properties for liquid crystal (LC) molecules adsorbed on a solid substrate, using dual polarization interferometry (DPI). A new theoretical framework is designed based …

Probing valley and magnetic photoexcitations in 2D crystals and their heterostructures
… MoSe2 to the picture, forming MoSe2/WSe2 heterobilayers in which we reveal the valley-contrasting physics of long-lived free and trapped interlayer excitons. Next, we introduce atomically thin CrI3 and describe our observation of spontaneous circularly polarized photoluminescence. We also unravel …
