The research team discovered that they could selectively control the property of semiconducting and metallicity according to the deposition temperature synthesizing MoTe2 by chemical vapor deposition. Furthermore, the researc

Graphene has gathered expectations as a new material that is perfect for electric devices. There was one problem. Graphene has no band gap which can control electric flow. Professor Cho Kil-won’s team (CE) composed graphene into a bernal-stacked multilayer, giving it a band gap to solve the problem. This was possible using a catalyst made by attaching a thin film of nickel onto the copper circuit board, controlling the number of layers. Prof. Cho said, “Band gap controlling is a source technology related to commercialization, and is expecting it to make great contributions in developing flexib

Recently, Professor Kim Jong-hwan (MSE) approached to advanced valley control through a group research project with UC Berkeley. Valley is a feature of electrons that was recently researched.
