Research Interest:

Research field covers mainly electronic absorption and emission spectroscopy; laser spectroscopy; studies on clusters; semi- and photoconductivity of organic, organometallic and polymeric materials; adsorption- induced phase transition; current oscillations in semiconductors; photoinduced phase transition; photoinduced charge-transfer; biosensors; molecular electronics etc.

Future Research Plan:

Research and development related to molecular controlled electronic and optoelectronic devices; studies on optical and electrical properties of nanostructured materials; studies on clusters of organic molecules using Laser Raman Spectroscopy and also by using Supersonic Jet Expansion technique, short wavelength vacuum ultraviolet laser and Time-of-Flight Mass Spectrometer.
