Ivan A. Pshenichnyuk, Gleb I. Nazarikov, Sergey S. Kosolobov +2
An efficient electro-optical modulation has been demonstrated here by using an edge plasmon mode specific for the hybrid plasmonic waveguide. Our approach addresses a major obstacl…
Subsurface diffusion in crystals and effect of surface permeability on the atomic step motion
S. S. Kosolobov
Atomic mechanism of the bulk and surface point defect generation and annihilation on surface sinks is considered theoretically on the base of the Burton, Cabrera and Frank model. W…
Real-Time Observation of Self-Interstitial Reactions on an Atomically Smooth Silicon Surface
Sergey Kosolobov, Gleb Nazarikov, Sergey Sitnikov +3
Self-diffusion and impurity diffusion both play crucial roles in the fabrication of semiconductor nanostructures with high surface-to-volume ratios. However, experimental studies o…
