Honorary Research Fellow PhD Physics, Ioffe Physico-Technical Institute of the Russian Academy of Sciences (St.-Petersburg, Russia), 1996 email: Konstantin.Pavlov@sci.monash.edu.au

High-resolution X-ray diffraction synchrotron experiments (Reciprocal Space Mapping) were conducted to investigate the structural quality of Aluminium Nitride and Gallium Nitride layers, which are used for production of blue light emitters.. This study of nanoscale objects generated in semiconductor materials is heading towards producing entirely new device structures relevant to the frontier technologies of photonics and quantum information processing.

RESEARCH INTERESTS

Dr. Pavlov’s main research interests include phase-contrast imaging, diffraction tomography, holography, statistical X-ray diffraction theory, X-ray characterisation of semiconductor structures.

Currently, Dr. Pavlov's research is focused:

• • To develop a comprehensive theoretical description of phase-contrast analyser/ propagation-based X-ray imaging and holography for attenuating objects.
• • To realise experimentally phase-contrast imaging and holography with high precision experiments using synchrotron sources.
• To study multilayer semiconductor structures, containing quantum-size objects , by high resolution X-ray diffractometry.
