Advanced Nano Technology (ANT) Laboratory
Welcome
Our group pursues a truly multidisciplinary effort focused on understanding physics and chemistry of materials at small scales and opening up new opportunities in a variety of engineering applications. In particular, we study low dimensional nanomaterials that mainly involve two-dimensional nanomaterials such as graphene, graphene-derived family, transition metal dichalcogenides (MoS2, MoSE2, WS2..etc.) and hexagonal boron nitride. Multifaceted R&D approach is implemented to develop leading technologies, by incorporating advanced nanofabrication, multi-modal imaging/characterization (topography/mechanical/chemical/electrical) and theoretical modeling.
Five main research areas include:
Advanced nanoscale manufacturing using focused energetic particle beams
Engineering of 2D nanomaterials and their applications
Solution-processed 2D nanomaterials and their applications
Correlative nanoscale imaging and characterization
Misc.: Mechanical design and analysis, Mechanical surface coating (carbon-based materials other than graphene)
