Research Topic

Crystal Growth Technology

The performance of electronic or optoelectronic devices often relies on substrate quality. The substrates are usually single crystals and can be grown by several methods from the melt, solution, or vapor. Our research interests for crystal growth include: (1) transport and interfacial phenomena; (2) process simulation; (3) crystal growth of new materials, such as organic semiconductors and nonlinear optical materials.


Electronic Materials Processing

There are several physical and chemical unit processes in electronic materials processing and device fabrications. We are interested in using computational fluid dynamics (CFD) to study these processes. Our current research topics include: (1) design and analysis of large-scale crystal growth furnaces; (2) processing through electromagnetic fields, vibration, and high-gravity, etc.; (3) vapor phase epitaxy.


CFD and High Performance Computing

With the fast development of computers and numerical methods, large-scale simulation has become an efficient way to understand and design a physical process. We are particular interested in developing high performance numerical methods, such as adaptive phase field simulation, for process simulation and nonlinear analysis.
