Personal profile
Research Interests
Professor Wessels’ laboratory develops thin films and nanostructures for electronic, magnetic, and photonic materials applications, with emphasis on semiconductor and ferroic oxide thin films. They are now developing a new class of widegap compound semiconductors including perovskites for x-ray and gamma ray detection.
Thye have synthesized epitaxial oxides by metal-organic vapor phase epitaxy for applications in nanophotonics and nanomagnetics. Emphasis is currently on the development of ferroelectric oxide epitaxial thin films and photonic crystals. Development of thin film photonic crystals for electro-optic modulators, and optical amplifiers for photonic integrated circuits (PICs) is under way.
