Ján Greguš

Dr. Ján Greguš is a Researcher in the Department of Experimental Physics at the Faculty of Mathematics, Physics and Informatics, Comenius University in Bratislava, Slovakia. His work focuses on experimental physics with applications in materials science and nanotechnology.

Dr. Greguš's research interests include:

• Materials Science, particularly semiconductor physics and nanomaterials
• Photocatalysis and surface engineering of titanium dioxide structures
• Characterization of silicon-based materials and nanostructures
• Electrical properties of disordered systems
• Optical properties of nanostructured materials

His recent publications (2017-2022) demonstrate consistent research output primarily in materials science and condensed matter physics. The work shows particular emphasis on titanium dioxide nanomaterials for photocatalytic applications and silicon-based structures, with publications appearing in reputable journals such as Physical Review B, Ceramics International, and Dalton Transactions. His research bridges fundamental physics with practical applications in environmental technology and semiconductor development.

Dr. Greguš teaches practical courses in optics and computer hardware principles at Comenius University. His teaching schedule includes:

• Optics practical training (1-FYZ-321) on Tuesdays and Fridays
• Computer Principles - Hardware (1-AIN-140) on Wednesdays (every other week)

His collaborative research approach is evident from his publications, which frequently include multiple co-authors from what appears to be a research team at Comenius University. His laboratory work focuses on materials characterization using techniques including FT IR spectroscopy, plasma-assisted processing, and various nanomaterial synthesis methods.
