Black phosphorus

It is obtained by heating white phosphorus under high pressures . Phosphorene can be viewed as a single layer of black phosphorus , much in the same way that graphene is a single layer of graphite.

When it was discovered over a century ago, black phosphorus was considered relatively useless. Over the past five years, however, the engineers and chemists have become intrigued by the material for its potential as an ultra-thin semiconductor, possibly ushering in a new age of flexible and smaller .

Following graphene, MXenes, and transition metal dichalcogenides (TMDs), black phosphorus (BP) has recently been introduced as a new member of the 2D materials family. Recently, the intensified research in BP has been motivated not only by its appealing properties, such as tunable band gap and . The result has been that black phosphorus has now become the new darling of two-dimensional (2D) materials and the next hope for a post-silicon world. In phosphorus : Properties and reactions …is converted to a flaky black crystalline form, which somewhat resembles graphite.

This may prove to be the most stable form of phosphorus , despite the relative difficulty in its preparation. In both the red and the black forms, each phosphorus atom forms three single bonds, which . Several good reviews have been published in the past two years either concerning its physical and mechanical . Abstract: We review the basic optical, electronic, optoelectronic, thermoelectric and mechanical properties of few-layer black phosphorus (BP), a layered semiconductor that can be exfoliated from bulk BP, the most stable allotrope of phosphorus.

A new tuning knob to modify the band gap of black phosphorus has been experimentally demonstrated. Comments: News and Views article. Many theoretical studies have predicted the anisotropic optical . Mass fabrication of two dimensional materials with a desirable thickness using a highly efficient and low-cost approach is ideal for industry applications. In this article, a two-step thermal annealing method is reported to prepare thickness controlled black phosphorus (BP) flakes under moderate temperature.

The Hall constant of the same material has been measured as a function of temperature at atmospheric pressure. However, the rapid degradation of BP under ambient air limits further research on its properties and implementation in various fields. This degrading behavior lowers the performance of BP-based . This review covers recent research work on the preparation, the crystal structure, the band structure, the electrical and optical properties, and the. Black phosphorus (BP) has attracted significant attention due to its excellent optical and electrical properties.
