Growth of phosphorene

Over the last decade, the research in 2D materials has grown appreciably, due to their new hitherto unknown properties as well as their great promise for application in next generation electronic and optoelectronic devices. In particularly, phosphorene has attracted intensive interest recently because it 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 crystals, and high carrier mobility with high on/off ratio. All these attributes make it suitable for nano-scale devices.

In this thesis, we present an experimental investigation of the epitaxial growth of phosphorus on Au(111) and Ag(111) substrates. The experiments were performed using the following ultra-high vacuum surface science techniques : scanning tunneling microscopy and spectroscopy (STM-STS), low energy electron diffraction (LEED), Auger electron spectroscopy (AES), x-ray photoelectron spectroscopy (XPS) and angle resolved photoemission spectroscopy (ARPES).
