Welcome
Two Dimensional Materials Research Group is led by Dr. Lain-Jong Li (Lance Li) at Institute of Atomic and Molecular Sciences, Academia Sinica , Taiwan. We are focusing on exploring fundamentals and applications of graphitic carbon materials, including carbon nanotubes and graphene.


Carbon Nanotubes
Transistors: Full semiconducting SWNT network transistor device yield was achieved by solution processed SWNTs. Mobility up to 10 cm2/Vs. (Chem. Comm. 2009) ( Adv. Mater. 2010)
Single Chirality of semiconducting tubes:
using fluorene polymer to selectively wrap (7,5) SWNTs (Nano
Lett. 2007)

Graphene
Direct Growth on Insulators: (Nano Lett. 2011)

Band Gap Opening with Molecular Doping: electrical On/Off current is improved and band gap is up to 110 meV. (ACS Nano 2011)

Symmetry breaking:
G-phonon splitting was induced by from molecular adsorption on graphene
