Quantum photonics and nanostructures

Previous and Current Research

Study of the fundamental properties of localized and collective coherent electronic excitations, their interaction with visible and infrared radiation in metal-semiconductor and metal-dielectric nanostructures with the aim of their practical usage in photovoltaics and for the sensors creation.

-        In Au/GaAs metal-semiconductor structures, a photocurrent has been recorded at photon energies below the GaAs bandgap (Fig. 1).

-        For the first time at room temperature without usage of fluorescent dyes, plasmonic enhancement of photoluminescence (PL) of the nucleotide dAMP on a hybrid plasmonic metasurface was achieved: 1120-fold gain of PL - for the metasurface Ag laser-induced periodic surface structure (LIPSS) /Ag nanoprisms (NP), 1220-fold - for the metasurface Ag LIPSS /Au nanorods (NR). This effect is due to: (i) the near-field plasmonic coupling in LIPSS with the formation of collective plasmon mode and (ii) the highest concentration of "hot spots" on LIPSS and NR (Fig. 2). (in corporation with Prof. Yeshchenko O.A. team)

-        The impact of femtosecond (fs) laser radiation on different materials has been studied, namely on noble metals (Au, Ag), ductile metals (Cu, Al), refractory metals (W, Mo), alloys, semiconductors with direct band gap (ZnSe, GaAs, CdZnTe), with the structurally induced direct-to-indirect band gap transition (PbI₂, GaSe) and indirect band gap (Si). The dependence of the periods of LIPSSs formed on metals (Cu, Ag, W) on the wavelength of irradiation has been studied. For the first time, LIPSSs on the PbI2 semiconductor was formed with a femtosecond laser radiation (800 nm), as well as LIPSSs on metals (Cu, Ag, W) under the 3rd harmonic of the fs laser (266 nm).

Future Projects and Goals

• The study of the effectiveness of the interaction of electromagnetic radiation with matter placed in/on the nanostructured by various methods metasurfaces of various types of plasmonic metal, semiconductor and hybrid metal-semiconductor elements, which provide a highly localized amplification of the electromagnetic field, as well as an amplification of the nonlinear optical response of the system. In particular, the possibility of the creation of a new type of plasmon sensors based on the phenomena of surface-enhanced upconversion and second harmonic generation will be studied.

• The study of a novel composite paints containing the perovskites quantum dots as a novel photoactive layer in thin film solar cells.

• Laser spectroscopy of highly excited semiconductors: studies of the excitonic processes in solid state; nanoparticles; clusters.

• Ultrafast spectroscopy of semiconductors and nanoparticles.
