Welcome
Exploratory Device Research Lab (ExDRL) is dedicated to explore groundbreaking device ideas based on exotic materials and/or novel concepts of device operations.
We are actively looking for highly motivated graduate and undergraduate students with a background in Electrical Engineering, Materials Science and Engineering, Physics, or related discipline. If you are interested, please send me your CV and transcripts by email (jiwonchang at yonsei.ac.kr).
Currently, we have two openings for the following research topics.
Density functional theory calculations for high-k gate stacks and dopant diffusion
Required Background: Quantum Mechanics, Solid State Physics, Python
Development of advanced FETs simulators based on Semi-Classical Monte Carlo approach
Required Background: Quantum Mechanics, Solid State Physics, C++, Python, Machine Learning
Development of process simulator (Industry Project)
Required Background: C++, Python, Machine Learning
I strongly recommend you to do your intership in our lab at least for two semesters before joining.
