Dr. Yuan Li discussed “Narrowing 2D to 1D: exploration of TMD nanoribbons” at the MRS 2016 spring meeting, symposium NT4.

The following is a brief summarization of Dr. Yuan Li's  talk.  

Atomically thin two-dimensional (2-D) structures, such as layered transition metal dichalcogendies (TMDCs) and black phosphorus (BP), are being explored as potential candidates for future nanoelectronic devices due to their unique physical/chemical properties and intrinsic band gap. However, thermal transport in various 2-D materials beyond graphene have not been well-studied and their concrete thermal conductivity was not experimentally valued. In this presentation, we report a series of our research focused on developing a reliable temperature-dependent Raman spectroscopy for understanding the unique thermal conduction performance MoS2 nanoribbons. The nanoribbons of MoS2 were fabricated using a mask-controlled photolithography technique. Considering their anisotropic in-plane thermal conduction property, a Raman spectroscopy equipped with polarized laser were used to determine their thermal conductivity. Our studies provide fundamental understanding on the unique thermal conduction of 2-D structures and are possible to give inspiration for the real fabrication of their nanoscale electronic devices where thermal management is critical.
