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 and silicon; investigates heat transport across/through semiconductors; efficiency droop mechanisms and remedies in AlInGaN emitters; and ultra-fast THz photonics/electronics.

Teaching Statement

Semiconductor fundamentals are essential in understanding everyday electronic and photonic devices. Undergraduate education should provide a solid foundation in semiconductors and should relate to everyday solid state devices. My goal as an instructor is to get students explain device behavior from the atomic scale up. I achieve this via first motivating the class for the big picture and then focusing on the atomic scale and describing atomic interactions leading to macroscopic effects observed in solid state devices. By building up the device behavior through atomic engineering, students understand the fundamentals governing everyday semiconductor devices such as light emitting diodes, solar cells, and transistors. It is notable that underlying physics, engineering, and science of solid state devices remain the same half a century; however, their applications, which I deem most important as an engineering faculty, diverse speedily. I see my role as a faculty not only to teach the fundamentals to the students but also making them aware of many out-there opportunities in the world. In the midst of fast-paced technology, one way to enable this is updating teaching tools and course materials. My instruction is geared towards enabling students become aware that microelectronics and photonics field is beyond the conventional solid state device applications and exciting them into the emerging interdisciplinary areas. I firmly believe teaching and research go hand-in-hand. I bring real-life problems to the classroom. Students need to leave their comfort zone, forego the classical classroom mentality, and look at tomorrow's needs via extending their knowledge, skills, and self. I bring fundamental knowledge, updated tools, and targeted means to the classroom for them do so.

Research Statement

Our current research interests lie in the intersection of novel III-V materials and hetero-structures & photonic and electronic quantum devices. Particularly, we explore novel materials, devices, and their 3D hetero-integration on unconventional platforms such as graphene and silicon, heat transport across/through semiconductors, efficiency droop mechanisms and remedies in AlInGaN emitters, and ultra-fast THz photonics/electronics. Our work is interdisciplinary. Our team demonstrates strong skills in solid state physics, first principles calculations, Technology Computer Aided Design, micro/nano-fabrication, and reliability characterization and analysis of semiconductor devices.
