Prof. Bayram is an expert in III-V materials & photonic and electronic devices. He has personally performed more than 3,000+ epitaxial growths with metalorganic chemical vapor deposition systems and fabricated detectors, light emitting diodes, solar cells, resonant tunneling diodes, and transistors in class 100 and 1000 cleanrooms totaling 20,000+ hrs equipment usage. His current research interests lie in the intersection of novel III-V materials, hetero-structures, and photonic and electronic quantum devices. Particularly, his research group explores novel materials, devices, and their 3D hetero-integration on unconventional platforms such as graphene, silicon, and diamond; investigates heat transport across/through semiconductors; efficiency droop mechanisms and remedies in AlInGaN emitters; and ultra-fast THz photonics/electronics.

Teaching Statement

The 21st century is the age of semiconductors. In all aspects of modern life, we utilize semiconductor technologies. From lighting to communication and computing to transportation, we rely on semiconductors for comfort, safety, and sustainability. Today, we are switching to solid-state lighting for halving our lighting electricity usage, 5G communication for networked devices, and autonomous systems for land/sea/air transportation. Our reliance on semiconductors is only to evolve as solid-state lighting extends into horticulture and medicine, new communication spectra above 95 gigahertz open opportunities for 6G and beyond networking, and space exploration leads to space settlements. Thus, it is imperative to understand, control, and exploit semiconductor technologies and to create an innovative education platform considering the needs of not only the current but also of the next generation.

Research Statement

The fundamental particle of optics, a photon, is unique as it rarely interacts with other fundamental particles. If a photon hardly interacts with another photon or an electron/hole, how can we create photons of interest efficiently? The answer is through man-made semiconductor materials. I research electron/hole and photon interactions in semiconductors and use the emergent understanding to design novel semiconductors and semiconductor devices. Particularly, I engineer semiconductor quantum structures with unique electronic band properties for high-speed transport and energy states for ultraviolet, visible, and terahertz optical transitions.

Post-Doctoral Research Opportunities

Our group might have an opening for a postdoctoral researcher who has HANDS-ON experience in the micro/nano-FABRICATION of compound semiconductor devices (including light emitting diodes and transistors based on GALLIUM NITRIDE devices) in a cleanroom environment. Postdoctoral candidates are encouraged to contact Prof. Can Bayram directly via email (and should attach their CV and the contact information for at least two references) to inquire about any position/project openings.

Graduate Research Opportunities

Our group is inviting undergraduate and graduate students to apply for PhD thesis openings in the areas of (a) Novel III-V materials and hetero-structures, and (b) Photonic and electronic quantum devices. Incoming and/or interested graduates are encouraged to browse our group webpage and contact Prof. Can Bayram directly via email (and should attach their CV and unofficial UG/GRAD transcripts) to inquire about any position/project openings.

Undergraduate Research Opportunities

Our group is inviting highly motivated undergraduates, currently enrolled at our University of Illinois at Urbana-Champaign, to join our research team. Particularly, students who wish to have experience in semiconductor devices and who are passionate about creating next generation photonic and micro/nano-electronic devices are welcomed. Historically, students who joined our research team as early as in their freshman/sophomore years authored journal papers by the end of their senior years. Please contact Prof. Can Bayram directly via email (and attach your CV and unofficial transcript showing your courses) to inquire about our any position/project openings.
