Occuring monthly during the academic year, the 2DCC Webinars present new technical scientific news from within the 2DCC facility and the broader scientific community, as well as, broader topics such as science related to diversity. The webinars are free with an online registration. The slides with voice-over for the 2016 webinars, 2017 webinars, and 2018 webinars are available by following the links in the left menu. Information regarding the next scheduled webinar is listed below.

“Strain and Isotopic effects in WSe2”
Dr. Michael T. Pettes
Scientist 3, Center for Integrated Nanotechnologies, Materials Physics and Applications Division, Los Alamos National Laboratory
Control over disorder arising from nonequilibrium of atomic positions and distributions of mass offers a promising route to design nanomaterial properties for integration into a wide range of existing and future applications. I will discuss our recently developed method to create highly-spatially localized and well-separated emission sites in a continuous film of nominally bilayer WSe2 using an ultra-sharp dielectric tip array where we have measured a second order photon correlation parameter to be below 0.3. I will also discuss our very recent discovery of the isotope effect in bilayer 186W80Se2, which is the first report of isotope engineering in a transition metal dichalcogenide (TMD) two-dimensional material. These discoveries have general implications to defect engineering, and hence impact varied and promising technological areas from energy conversion to quantum communication.
