High-Pressure Studies On The Transition From Red Phosphorus To Black Phosphorus, Heng Xiang
High-Pressure Studies On The Transition From Red Phosphorus To Black Phosphorus, Heng Xiang
Electronic Thesis and Dissertation Repository
Black phosphorus (BP) is a promising material in many research fields. However, the transition process from amorphous red phosphorus (ARP) is elusive and hence hinders large scale synthesis and applications. This work describes the application of the high-pressure method to study the transition process from ARP to BP.
In this thesis, the following three objectives were achieved: (1) to understand the mechanism of the transition, (2) to facilitate the synthesis of BP by taking the advantage of less pure ARP, (3) to propose new methods of synthesizing BP-based materials, such as the moderately oxidized BP and the black phosphorus/ amorphous …
