His area of interest focus on designing nanostructured materials withapplications in electronics and clean energy generation.

报告摘要：

2D carbon and transition metaldichalcogenides (TMD) materials have attracted much attention due to theirunique properties, ranging from low dimensional effects, good structuralintegrity, high electrical and thermal conductivity, and chemical stability.Increasingly, the applications of these materials have gradually progressedinto different areas ranging from electronics to conductive coatings tobiomedical technology.

In this talk, we will show through rationaldesign, we can engineer these low dimensional materials through differentgrowth techniques and obtained the required structure and morphology thusachieving the desired results, for example as better electron emitters usinglow temperature growth of graphene directly on nanospindt tips. Through acombination of bottoms-up and top-down approach, we are able to engineervarious 2D compounds into core-shell and other type of hybrid structures, A fewexamples such as high mobility plate-like structures of MoO3 and memory effectsof 2D CuS will be shown.
