Abstract: Phosphorus is one of the most abundant elements preserved in earth, constructing with a fraction of 0.1% of the earth crust. In general, phosphorus has several allotropes including white, red, and black phosphorus. Black phosphorus, though rarely mentioned, is a layered semiconductor and have great potentials in optical and electronic applications. Remarkably, this layered material can be reduced to one single atomic layer in the vertical direction owing to the van der Waals structure, dubbed phosphorene, where the physical properties can be tremendously different from its bulk counterpart and needed to be further explored. In this talk, we trace back to the 100 years research history on black phosphorus from the synthesis to material properties, and extend the topic from black phosphorus to phosphorene. Their electrical, optical, thermal and mechanical anisotropic properties are thoroughly studied and will be presented and reviewed.
Biography: Peide Ye is Richard J. and Mary Jo Schwartz Chair Professor of Electrical and Computer Engineering at Purdue University in USA. He received Ph.D. from Max-Planck-Institute of Solid State Research, Stuttgart, Germany, in 1996. Before joining Purdue faculty in 2005, he worked for NTT, NHMFL/Princeton University, and Bell Labs/Lucent Technologies/Agere Systems. His current research is focused on ALD high-k integration on novel channel materials including III-V, Ge, complex oxides, graphene and other 2D crystals. He authored and co-authored more than 150 peer reviewed articles and 300 conference presentations. He is a Fellow of IEEE.
