A research team led by Professor Im Seong-il from the Institute of Physics and Applied Physics has demonstrated a process for using only ‘Van der Waals force’ in a functioning semiconductor device. ‘Van der Waals force’ refers to the residual attractive or repulsive forces between molecules or atomic groups. Their results were published March 16 in the online version of Advanced Functional Materials under the title “Non-Lithographic Fabrication of All-2D α-MoTe2 Dual Gate Transistors.”
