Dr Yuerui (Larry) LuOutline:
Two-dimensional (2D) nano-materials, such as molybdenum disulfide (MoS2) and graphene, have atomic or molecular thickness, exhibiting promising applications in nano-electro-mechanical systems. Graphene is a one-atom thick carbon sheet, with atoms arranged in a regular hexagonal pattern. Molybdenum disulfide (MoS2) belongs to transition metal dichalcogenides (TMD) semiconductor family YX2 (Y=Mo, W; X=S, Se, Te), with a layered structure. These 2D nano-materials can be integrated into nano-electro-mechanical systems, enabling ultra-sensitive mechanical mass sensors, with single molecule or even single atom sensitivities. Moreover, the mechanical resonators based on these 2D nano-materials would be a perfect platform to investigate quantum mechanics, opto-mechanics, material internal friction force, nonlinear physics, etc.
Requirements/Prerequisites
We are looking for highly motivated Ph.D. graduate students who are majoring in applied physics, electrical engineering, mechanical engineering, chemistry, materials science engineering, biomedical engineering, or other closely related areas to join the research team. We always look for dedicated undergraduate or master students to join us, to do creative work in rapidly growing field and generate co-authored publications.
