主　　题：two-dimensional material phosphorene exciton anisotropy 

摘      要：Phosphorene is a two-dimensional semiconductor with layers-dependent bandgap in the near-infrared range and it has attracted a great deal of attention due to its high anisotropy and cartier mobility. The highly anisotropic nature of phos- phorene has been demonstrated through Raman and polarization photoluminescence measurements. Photoluminescence spectroscopy has also revealed the layers-dependent bandgap of phosphorene. Furthermore, due to the reduced dimension- ality and screening in phosphorene, excitons and trions can stably exist at elevated temperatures and have large binding energies. The exciton and trion dynamics are thus detected by applying electrical bias or optical injection to the phospho- rene system. Finally, various optical and optoelectronic applications based on phosphorene have been demonstrated and discussed.
