Education

Self-intro:

Prof. Yongsheng Wang’s research is mainly based on Optoelectronic materials and its devices and applications on Micro/Nano scale.Two-dimensional layered semiconductors and their exciton dynamics are studied by transient microscope technique based on a femtosecond laser system. The result that optical properties of tungsten disulfide can be effectively tuned by carriers in graphene is found. Also, in searching of ultrathin materials with high mobilities and unable band gaps, black phosphorus is measured with a high mobility of 104cm2V-1s-1, which shows black phosphorus is a promising candidate for future electronic and optoelectronic applications. Other projects are also conducted, including organic electroluminescent devices based on graphene, solar cells, supercapacitors, lithium ion batteries, optical modulator and so on. During last 5 years, more 100 papers have been published, 80 papers have been included in SCI, 11 invited reports have been given at domestic or abroad,and 11 patents have been applied including 4 of them obtained authorisation.
