Two-Dimensional Materials
Growth | Characterization | Application
My research interests center around the synthesis, characterization, and applications of high-quality two-dimensional (2D) materials, particularly graphene, hexagonal boron nitride (hBN), and transition metal dichalcogenides (TMDs), using chemical vapor deposition (CVD) growth. I am particularly interested in studying the growth mechanism, substrate engineering, and morphology control of these materials, with a focus on achieving direct synthesis on insulators. Additionally, I am well-versed in various characterization techniques such as optical microscopy, Raman spectroscopy, and scanning electron microscope (SEM), which I employ to assess the crystal quality and physical properties of 2D materials. Overall, my aim is to advance the field of 2D materials and explore their potential applications in electronic and optoelectronic devices.

Research Topic
-
2D Materials synthesis
Our research focuses on the synthesis of 2D materials using chemical vapor deposition (CVD) methods. Specifically, we aim to fabricate large-scale, high-quality 2D materials such as graphene, hBN, and TMDs. These materials have unique electronic, optical, and mechanical properties, making them attractive for a wide range of applications.

CVD Growth Mechanism
To achieve high-quality 2D materials, it is crucial to understand the underlying growth mechanism in the CVD process. To this end, we combine numerical simulations with experimental results to investigate the growth mechanism of 2D materials. Our goal is to optimize the CVD growth process to achieve high crystal quality and large-scale synthesis of these materials.

Substrate Engineering
The substrate plays a critical role in the growth of 2D materials. We are studying substrate engineering for the epitaxial growth of 2D materials on both metal and insulating substrates. Specifically, we investigate substrate treatment methods to optimize the growth of these materials. Our aim is to develop efficient and effective methods to grow high-quality 2D materials on different substrates.

Growth on Insulators
The direct or indirect growth of graphene on insulating substrates is a challenging task. We are exploring ways to achieve this goal, focusing on substrates such as sapphire, SiO2/Si, and quartz. Our aim is to develop a reliable and efficient method to grow graphene on insulating substrates, which could expand the potential applications of graphene in future electronics.
