Siddharth Rajan

Siddharth Rajan is a Distinguished Professor of Engineering at The Ohio State University, jointly appointed in the Department of Electrical and Computer Engineering and Materials Science and Engineering. He joined Ohio State in 2008 after receiving his PhD from UC Santa Barbara in 2006 and research roles at UC Santa Barbara and GE Global Research. His expertise spans semiconductor materials and devices, with a focus on wide-bandgap semiconductors (GaN, AlN, Ga₂O₃), molecular beam epitaxy, power/RF electronics, and optoelectronics.

Rajan leads a dynamic research group specializing in semiconductor heterostructures, epitaxial growth, and advanced device fabrication. Key research areas include:

• High-frequency mm-wave/RF devices
• Energy-efficient power electronics
• Visible/UV optoelectronic systems
• Novel materials engineering (e.g., β-Ga₂O₃, AlGaN)

His publications demonstrate a strong emphasis on tunnel junctions, heterostructure design, and high-breakdown field devices, with consistent themes in efficiency optimization for LEDs and transistors.

Rajan has received numerous awards, including:

• NAMBE Young Investigator Award (2017)
• Harrison Award for Research Excellence (2018)
• JSAP Outstanding Paper Award (2018)
• Multiple Best Student Paper awards (2006, 2008, 2013)

He actively advises PhD students, with recent graduates focusing on GaN power devices, UV LEDs, and oxide semiconductors. His lab utilizes specialized facilities for epitaxial growth and device characterization, supported by grants from agencies like the DOE.
