| Abstract: |
| Single layer black phosphorus was named as phosphoren, which has several properties that distinguish it from other 2D materials, including an intrinsic direct band gap, that can be tuned from 1. 8 eV for a monolayer to 0. 35 eV for bulk black phosphorus crystalsand high carrier mobility with high on/off ratio, high optical and UV absorption , and other attractive properties. These properties make phosphorene promising for applications in nano electronic and nano-optical devices. Inspired by the investigation of black phosphorene, a new attractive 2D phosphorus allotrope, blue phosphorene, has been predicted theoretically, which shares many excellent characteristics as black phosphorene with the buckled honeycomb lattice. Although phosphorene possesses attractive mechanical, electronic, optical and transport properties, the synthesis of phosphorene is still a major challenge. Herein, we summarize and highlight the recent progress in phosphorene research touching upon topics preparation, isolation, characterization and properties, and also provide our insights and outlook on the future problems and challenges in phosphorene research. |
