R&D reported that for the first time, researchers at the US Department of Energy’s Lawrence Berkeley National Laboratory have observed a “strong nonlinear resonance along the edges of a single layer of molybdenum disulfide.”

R&D reported that for the first time, researchers at the US Department of Energy’s Lawrence Berkeley National Laboratory have observed a “strong nonlinear resonance along the edges of a single layer of molybdenum disulfide.”

As quoted in the market news:

The existence of these edge states is key to the use of molybdenum disulfide in nanoelectronics, as well as a catalyst for the hydrogen evolution reaction in fuel cells, desulfurization and other chemical reactions.

Xiang Zhang, a faculty scientist with Berkeley Lab’s Materials Sciences Division, commented:

We observed strong nonlinear optical resonances at the edges of a two-dimensional crystal of molybdenum disulfide. These 1-D edge states are the result of electronic structure changes and may enable novel nanoelectronics and photonic devices. These edges have also long been suspected to be the active sites for the electrocatalytic hydrogen evolution reaction in energy applications. We also discovered extraordinary second harmonic light generation properties that may be used for the in situ monitoring of electronic changes and chemical reactions that occur at the 1-D atomic edges.
