Taekjib Choi

Taekjib Choi is a Professor in the Department of Nano Technology and Advanced Materials Engineering at Sejong University, South Korea, holding this position since 2011 after serving as a Research Fellow at Oak Ridge National Laboratory (2010-2011). He earned his Ph.D., M.S., and B.S. from Sungkyunkwan University in 2007, 2002, and 2000 respectively.

His educational background includes:

• Ph.D. from Sungkyunkwan University (2007)
• M.S. from Sungkyunkwan University (2002)
• B.S. from Sungkyunkwan University (2000)

Dr. Choi's research focuses on nanotechnology and materials science with specialization in transition metal oxide systems. His core work spans:

• Fabrication of ferroelectric oxide thin films for non-volatile memory and photovoltaic devices
• Photoelectrochemical water splitting using oxide semiconductors and nanomaterials
• Electronic properties analysis of nanodevices via scanning probe microscopy

Recent publications (2024-2025) reveal dominant trends in memristive neuromorphic computing and advanced semiconductor materials, featuring HfO2-based trilayer memristors with oxygen vacancy engineering, high-κ SrTiO3 gate dielectrics for β-Ga2O3 transistors, low-k SiCOH film optimization, and NiMOF-LDH photocatalytic systems.

With 75 research outputs demonstrating consistent productivity (including 4 publications in 2025 alone), Dr. Choi maintains active supervision of graduate students and secures research funding, though specific grant details remain unreported. His work directly supports UN Sustainable Development Goals through clean energy and materials innovation.
