Center for Integrated Nanostructure Physics

Tremendous efforts have been devoted to research in two-dimensional (2D) nanomaterials and their devices. Recently, novel carbon allotropes such as graphene, fullerene, carbon nanotube, graphene nanoribbons, graphyne, and graphdiyne have been investigated due to their outstanding properties. Though, graphene is a remarkable material with great potential in many applications due to its semi-metallic nature, it is not good enough in organic field-effect transistors (OFETs). The bottom-up synthesis method of holey graphene/graphyne (HG/HGY) has recently attracted great attention owing to its potential application as an active component of field-effect transistors.

The prime goals of our research are the innovative design of such novel 2D molecules, development of their synthetic routes, characterization, studies of their properties, and potential applications in different fields (OFET, energy storage and conversion, etc.).

Our research group is focusing mainly on the following aspects of 2D materials chemistry:

• The novel bottom-up synthesis method of holey graphene/graphyne (HG/HGY), graphdiyne (GDY), characterization, studies of their properties and potential applications.

• The CVD synthesis method of holey graphene/graphyne (HG/HGY), and graphdiyne (GDY).

• Apart from the aforementioned research topic our group is also interested in the synthesis of polyatomic hydrocarbon (PAH) by a combined in-solution and on-surface synthesis method.
