Научные интересы: From 1986 - till the present time - work in the fields of scanning probe microscopy, spectroscopy and physics of nanostructures
1. The high-precision STM/STS, AFM and SNOM devices were constructed. Low temperature STM (LT STM) with special stage for sample cleaning by in situ cleavage was built. LT STM operates at low temperatures, ultrahigh vacuum and high magnetic fields. Multi-purpose SNOM for both scanning probe and scanning sample modes may be used at ten optical configurations (including polarization modes).
2. The mechanism of the tunneling in the nanometer size structures produced by clusters or thin polymeric Langmuir-Blodgett (LB) films was studied. Charge density waves (CDW) and induced conductivity of films were discovered.
3. A comparison of localized state density for SiO2--SiO:H and LB films of comb-like polymer -Si:H interfaces has been made by means of STM. The carrier mobility of the channel realised along the LB film was found to be 30 times greater then in that along the SiO2.
4. A procedure for controlled transfer and sedimentation of separate molecules has been elaborated. Conducting channels in such molecules were discovered and their properties were investigated by means of STM/STS. (1988- in List of publications No.22 )
5. The surface enhancement of non-linear-optical effects on monoatomic surface layers was studied by means of STM and reflected second harmonic (RSH) generation.
6. The method of spectroscopy within the framework of Atomic Force Microscopy was offered.
The limitation on the parameters of Yukawa long-range interaction was received from atomic-force microscopy experiment (testing of gravitational theories ).
7. The first observation by STM of the smallest carbon rods (tubelenes C36+12) having the diameter 0.8 nm on nanofilament films, prepared by vacuum electron beam graphite evaporation, has been made.
8. New dimensional quantization effects (DQE) in the vicinity of artificially produced clusters on semiconductor surface and near nanodefects on HOPG surface were observed by means of STM/STS. It was shown than the interaction between neighbouring defects can lead to DQ level splitting. The effects have local character and differ from 'zero anomalies' often observed in tunnel junctions.
9. The influence of the Coulomb interaction of localized charges on scanning tunneling spectra of surface nanodefects was discovered and investigated. The shapes of tunneling spectra were explained taking into account finite relaxation time of nonequilibrium electrons and presence of localised states.
10. Light-induced conformational transformation of the naphthacenequinone (NQ) molecules is observed by scanning tunneling microscopy and spectroscopy. Additional sub-band of empty electronic states has been found for NQ molecules in A form and not found in B form. The conformational transformation is connected with the transfer of the phenoxy group from one oxygen to another.
11. The influence of resonant tunneling on the imaging of impurity atoms and defects on semiconductor surfaces was investigated by low temperature STM/STS. The anomalous effects of resonant tunneling channel switch on and off were observed. The effects were explained in the framework of nonequilibrium theoretical model of tunneling.
12. New nonequilibrium interaction effects of impurity atoms on semiconductor surface have been experimentally studied by means of STM/STS methods and theoretically analyzed using a self-consistent approach based on the Keldysh formalism.
13. Low-temperature method of identification of individual impurity atoms on a semiconductor surface by precision analyzing of local tunneling conductivity curves near impurities was developed. About 10 impurity atoms on and under A3B5 semiconductor surface were investigated and found out that each atom has its own tunneling conductivity spectra.
14. Magneto-optical effects, domain and domain walls were investigated by means of polarization near-field microscopy with spatial resolution up to 20 nm.
15. Effects of polarization contrast have been found in reflection SNOM experiments.
16. Coulomb singularity effects in tunneling spectroscopy of individual impurities were observed.
