Nathan O'Brien

Nathan O'Brien is an Associate Professor in the Department of Physics, Chemistry and Biology (IFM) at Linköping University. His research focuses on materials chemistry, with particular emphasis on the synthesis and application of metal-based precursors for thin film deposition techniques such as Atomic Layer Deposition (ALD) and Vapor Deposition. He has contributed significantly to the development of novel triazenide-based precursors for semiconductor materials like indium nitride and gallium nitride, addressing challenges in high-frequency electronics and optoelectronics.

Key research interests include inorganic chemistry, semiconductor materials engineering, and the design of cost-effective precursors for advanced thin film technologies. His work bridges fundamental chemical synthesis with applied materials science, aiming to improve the quality and scalability of electronic materials.

Notable achievements include the development of a zinc triazenide precursor for vapor deposition and the synthesis of semi-transparent SrTaO₂N photoanodes with GaN underlayers. These innovations highlight his expertise in both materials synthesis and functional device applications.

Dr. O'Brien collaborates extensively with researchers in chemistry and physics, contributing to interdisciplinary projects at LiU. His publications reflect a strong focus on thin film growth mechanisms, precursor thermal stability, and semiconductor material characterization.
