Home of Nanoelectronic Materials

Our main research interest is to develop, modify and understand nano-material systems that are applicable to semiconductor devices.

For this, we largely focus on the synthesis of electrically conductive molecular crystals, organic/inorganic thin films, and 2D materials.

Organic semiconductor

Radical crystal

Chemical doping

Vapor phase chemical reactions

Metal organic frameworks

Covalent organic frameworks

Lattice-doped graphene

Twisted bilayer graphene
