CVD team research

Our team are synthesizing nano-materials such as Graphene, Nb Compounds, and V Compounds using CVD technique.

CVD(Chemical Vapor Deposition) is a widely used materials-deposition and synthesis technique. It has been used for a very wide range of materials such as pure elements, and compounds.

 In CVD system, precursor gas which is containing element to be deposited or element in desired compound is flowed into a heated chamber. Chemical reactions occur on and near our target substrate.

CVD method has a number of advantages for synthesis of materials. One of the main advantages is that process parameters such as gas flow rate and heating temperature can be precisely controlled, and the quality of synthesized material is very high accordingly.

Using CVD technique, our team have synthesized high-quality single-crystal monolayer Graphene, large-scale Graphene, Graphene directly grown target substrate, and Nb compounds(oxide, carbide, selenide).

Chemical team research

Main research of chemical team is 1D materials and new structural nanomaterials.

The goal of our research is the synthesis, fundamental investigation, and practical device application of novel one-dimensional (1D) materials that have a molecular chain structure with a diameter down to ~1 nanometer and no property degradation at the nanoscale, which have an inorganic molecular chain structure with dangling bond-free surface.

We synthesize molecular chain-aligned 3D bulk materials in which molecular chains are stacked in 3D crystal structure via a weak van der Waals attraction and then isolate 1D molecular chains from the 3D bulk materials by using chemical exfoliation and mechanical exfoliation. Also, by using 1D materials, we apply these novel materials to high performance devices, molecular devices and flexible/stretchable devices.

Meet Our Team

A total of 18 doctor candidate, master candidate and undergraduate students are in the process of realizing their dreams.
