We explore the novel functional properties of materials at nanoscale, energy storage and renewal energy conversion with reduced dimensions. Our research interest also focuses on fundamental understanding of nanoscale properties and fabrications to realize high-efficiency, low–cost energy-relevant devices. In-situ techniques also enable us to probe the physical and chemical processes of materials and device functions.
Two dimensional (2D) layered structure transition metal dichalcogenides (TMDs) have received much attention in recent years, because of their unique properties associated with their reduced thickness. We mainly focus on the 2D material synthesis, characterization and nanoscale device applications in electronics, optoelectronics, energy storage and energy conversion.
Transition metal doped semiconductors have been a major focus of magnetic semiconductor research. Diluted magnetic semiconductor bridges the semiconductors and ferromagnets, which provides ferromagnetic features in traditional semiconductors with a variety of new physical phenomena and functionalities. We focus on diluted magnetic semiconductor synthesis, characterization of novel properties and device fabrications.
To make the revolutionary breakthroughs needed to meet future energy application requirements, it is important to understand phase transition and carrier transport at the interface in the energy-relevant devices, which is an important key to the device performance, life time and safety. In-situ characterizations simultaneously allow for direct in-situ observation of the fundamental mechanisms in play. Utilizing the in-situ techniques, we are able to probe the processes of materials and device functions in real time.
