2 Dimensional Materials

After introducing graphene as a strong candidate as a 2-dimensional building material for advanced devices with outstanding properties, 2-dimension materials (graphene, MoS2, BN and etc.) have much attracted the scientific interesting. 2-dimension materials have not only superior intrinsic physic-chemical properties, but also show many physical phenomena that are observed barely in nature. In our lab, we focus on the study widely related 2-dimension material included fabrication, characterization and applications of them. Antecedently to all of studies, a fundamental exploration to 2-dimensional materials should be deliberated. We have basically fabricated 2-dimenstion materials by many methods. We are also interesting in intrinsic optical and electrical properties of 2-dimension materials and have discovered them by physical measurement systems, which supply the scientific understanding and show the potential for applying to future devices. It While more work needs to be done before we can develop actual gadgets using new 2-dimenstion materials, this breakthrough lays the foundation for a new electronics and optics revolution. We look forward to exploring its potential. While more work needs to be done before we can develop actual gadgets using this new 2-D nano-material, this breakthrough lays the foundation for  a new electronics revolution and we look forward to exploring its potential.
