Classical-to-Quantum Crossover in 2D TMD Field-Effect Transistors: A First-Principles Study via Sub-10 nm Channel Scaling Beyond the Boltzmann Tyranny
Yu-Chang Chen, Chia-Yang Ling, Ken-Ming Lin
Scaling field-effect transistors (FETs) into the sub-10-nm regime fundamentally alters the transport mechanism, challenging long-standing design rules. This study investigates mono…

Quantum transport calculations: An effective medium theory based on the projector augmented wave method with the plane-wave basis
Yi-Cheng Lin, Ken-Ming Lin, Yu-Chang Chen
We present an effective medium theory based on density functional theory that is implemented in VASP using the PAW method with a plane wave basis set. The transmission coefficient…

Thermoelectric optimization and quantum-to-classical crossover in gate-controlled two-dimensional semiconducting nanojunctions
Yu-Chang Chen, Yu-Chen Chang
We investigate the thermoelectric performance of 2D nanojunctions with gate tunable architectures and varying channel lengths from 3 to 12 nm using a combination of first principle…
