On the verge of 21st century, graphene emerged as a new world of materials. Electronic properties and photoexcited carrier behaviour in the low-dimensional system are our main focus.

 

 2D Materials

Two-dimensional materials are in the form of ultrathin film of atomic layers such as graphene, metal dichalcogenides, silicene, and phosphorene. Many of them possess excellent carrier mobility, optical sensitivity, or resistance to mechanical deformation. The spatial confinement of 2D materials produces strong dependence of optical/electrical properties on thickness. Those are why my researchers are interested in the fabrication and characterization, and future applications of 2D materials.

 Photochemical etching of Black Phosphorus Layers

Atomically thin layer fabrication of black phosphorus (BP) material was one of main obstacles ahead. We applied UV-generated ozone and water rinse on BP and successfully achieved well controlled film thickness. The final surface shows flat and oxidation-protective properties.(more)
