Research

We focus on 2-dimensional (2D) layered electronic devices as one of the most promising future options to enhance the device performance. Although 2D heterointerface is ideally expected to be electrically inert, the superior interface properties are blinded by the imperfection of 2D materials and the interaction with the surroundings. The key to improve the properties is to understand the interface properties between 2D layered materials and the surroundings and to control them from the viewpoint of material science as well as device physics.
