Rotation effect in optical imaging of symmetrical figures in an opaque screen
A. Bekirov, V. Sitnyansky, S. Senotrusova +3
A novel effect of rotation in the optical image of structures in an opaque screen is presented. Theoretical calculations and experimental validation are presented. The features and…
Optical super-resonances in dielectric microsphere particles
Zengbo Wang, Boris Lukyanchuk, Baidong Wu +5
Extreme field localization and giant field enhancement are often achieved by using plasmonic nanostructures and metamaterials such as strongly coupled silver nanoparticles.Dielectr…
T4 DNA condensation in water-alcohol media
M. O. Gallyamov, O. A. Pyshkina, V. G. Sergeyev +1
The process of compaction of high molecular weight DNA T4 is investigated directly in a AFM liquid cell. The AFM-images of globules formed by DNA molecules in the result of compact…
Quantitative methods for deconvolution of true topographical properties of object on the basis of measured AFM-images: Part 2. Broadening effect
M. O. Gallyamov, I. V. Yaminsky
Technique of the quantitative description of image broadening effect in AFM allowing to restore real geometrical parameters of object using two-parameters model (height and width a…
Quantitative methods for deconvolution of true topographical properties of object on the basis of AFM-images: Part 1. Contact tip-sample deformations
M. O. Gallyamov, I. V. Yaminsky
We assume that the sample height measured using AFM is reduced due to contact deformation. The Herz contact theory is applied for the quantitative description. General numerical so…
Visualization of atomic structure using AFM: theoretical description
M. O. Gallyamov, I. V. Yaminsky
We suggest simple model of image formation in atomic force microscope (AFM) taking into account contact deformations of probe and sample during scanning. The model explains the pos…
