Electrochemistry of materials and crystal growth: investigation of soft (electro)chemical methods intended to the controlled preparation and characterization of specific material microstructures, as well as the manufacture of heterostructures (metal-semiconductor, semiconductor-semiconductor, semiconductor-liquid junctions) featuring adjusted properties for technological applications. In particular:
- Synthesis of binary and ternary selenide and telluride compounds by electrochemical (constant and pulse current) deposition, chemical deposition, or hybrid techniques. The produced films in single and multiple layer configurations are evaluated as photovoltaic device components and also as electrodes in photoelectrochemical cell and photocatalytic applications.
- Electrochemical anodization of metals; production of porous oxides and investigation of optical sensitization effects in photoelectrochemical cells.
- Formation of simple and composite (polymer-reinforced) metallic coatings using constant and pulse current electrolytic techniques, and characterization of their microstructure in connection with mechanical properties and corrosion behavior. Theoretical and experimental study of the nucleation and crystal growth process.
Characterization and measuring techniques used in my research work include:
- Electrochemical methods, such as (photo)voltammetry, chronoamperometry, photocurrent spectroscopy, and electrochemical impedance spectroscopy.
- Solid state characterization: X-ray powder diffractometry (XRD), optical microscopy, Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Analysis (EDAX), micro-Raman and X-ray Fluorescence (XRF) spectrometry.
- Optical methods: absorption/reflection spectroscopy of thin films, modulation spectroscopy, UV-Vis and Atomic Absorption Spectrometry (AAS).
- Evaluation of semiconductor diode characteristics, Hall effect and surface conductivity measurements.
