Greetings! I'm Paul, I make advanced semiconductors

Doctorate in thin-film semiconductors with over 10 years of experience in solving material science research questions.

Material science I understand is the most fundamental form of engineering that interlinks the sciences with other application-driven engineering fields. From making novel nanocrystalline surface architecture for efficient charge-discharge dynamics in an energy storage cell, to making efficient infrared sensors that can observe the far reaches of the universe, the future of technology will come through material science.

Starting from my first project in 2010, where I studied the surface tension in different cooking oils to analyze the quantity of trans fatty acids present, to completing my Ph.D. in Ultra wide band gap semiconductor materials in 2023, material science has been the centerpiece of my research interests.

My expertise lies in

Crystal growth and lattice tuning
Nanocrystalline surface morphology tuning and analyses
Optoelectronic characterization and analysis
Cathode metal oxide active layer synthesis and structure optimization
Battery testing and analysis
Functional property analyses of doped and ternary metal oxide thin films
