Overview
Low dimensional materials such as graphene, hexagonal boron nitride and transition metal dichalcogenides (TMDs) have attracted enormous attention because of their unique electronic, optical, thermal, mechanical, and chemical properties. For these materials which have a high surface area to volume ratio, the role of the surface is important. Our laboratory focuses on understanding "What really happens on the surface of low dimensional materials".
Synthesis
Our laboratory has attempted various methods to synthesize high-quality low dimensional materials. Among them, chemical vapor deposition (CVD) has received considerable attention because of its possibility for the scalable production of high-crystalline materials. However, there are still unknown mechanisms on how these materials are synthesized on the substrate. We aim to identify and understand these growth mechanisms for the controlled growth of materials.
Analysis
To investigate the physical and chemical properties of low dimensional materials, various analysis methods are exploited. Moreover, to understand what really happens on the surface of low dimensional materials, spatially resolved surface characterization would be needed. We aim to get a deep insight into the low dimensional materials by using various analysis methods such as analytical electrochemistry, spectroscopy and microscopy.
Application
The extraordinary properties of low dimensional materials originated from the quantum confinement effect and the high surface area to volume ratio have the potential for application in diverse fields. To effectively utilize their unique property, we aim to apply low dimensional materials to diverse areas such as sensor, device, battery and electrochemical catalyst.
