What is special about phosphorene?

There is rising interest in phosphorene, a 2D monolayer of black phosphorus, for electronic applications in the post-graphene era. Phosphorene can be exfoliated from bulk black phosphorus in the same way as graphene from bulk graphite. Phosphorene is stable and, unlike graphene, displays a nonzero fundamental band gap. Early observations indicate that carrier mobility in phosphorene is rather high; even though it does not measure up to the semimetallic graphene, it appears to be superior to transition metal dichalcogenides such as MoS2.


Invited speakers (alphabetical):

Registered participants come from Canada, P. R. China, Germany, Ireland, Netherlands, Singapore, Spain, United States.


Scope:

The number of phosphorene studies has been skyrocketing since January 2014. Published manuscripts include

Likai Li, Yijun Yu, Guo Jun Ye, Qingqin Ge, Xuedong Ou, Hua Wu, Donglai Feng, Xian Hui Chen, and Yuanbo Zhang, "Black phosphorus field-effect transistors", Nature Nanotechnology 9, 372–377 (2014).
Han Liu, Adam T. Neal, Zhen Zhu, Zhe Luo, Xianfan Xu, David Tománek, and Peide D. Ye, "Phosphorene: An Unexplored 2D Semiconductor with a High Hole Mobility", ACS Nano 8, 4033–4041 (2014).
Zhen Zhu and David Tománek, "Semiconducting layered blue phosphorus: A computational study", Physical Review Letters 112, 176802 (2014).

Also the number of phosphorene studies posted on arXiv is increasing rapidly, including:

The rapidly rising interest in the field calls for an informal symposium, where researchers can freely exchange ideas and discriminate between more and less fruitful experimental and theoretical approaches.


Topics:

Discussions will focus on the following topics (non-exhaustive list):

  • Which techniques can be used to fabricate few-layer phosphorene?
  • How stable is few-layer phosphorene?
  • How to fabricate the best contacts to few-layer phosphorene?
  • Which is the intrinsic (phonon-limited) conductance of few-layer phosphorene?
  • How wide is the fundamental band gap and what is the exciton binding energy?
  • Can electronic and optical properties be tuned by the number of layers or in-layer strain?
  • Are there different structural allotropes of layered phosphorus beyond black phosphorus?
  • Can a particular structure of a monolayer be selectively synthesized by CVD?
  • Can we make use of lessons learned from graphene and transition metal dichalcogenides?

Format of the Symposium:

As a well-tested format, the symposium will be a combination of

  • invited talks by experts in phosphorene and related 2D materials,
  • short contributed talks addressing specific topics with ample time for discussion,
  • poster presentations possibly enhanced by the poster-PLUS format, and
  • afternoon-long discussions of specific questions.
