Topological Valleytronics in Bilayer Graphene

Tuesday, November 7, 2017

Speaker: Jun Zhu
Description: In this talk I will describe how we realize valley-momentum locked topological conducting channels in bilayer graphene and demonstrate the operations of a waveguide, a valley valve and tunable electron beam splitter, all of which are electrically controlled.

Intercalation, Exfoliation, Assembly of 2D Materials

Tuesday, May 30, 2017

Speaker: Thomas E. Mallouk
Description: A variety of physical and chemical methods have been developed to make colloids of nanosheets from bulk crystals of 2D materials. These 2D colloids provide an alternative to single sheets made by “scotch tape” or vapor deposition methods, and enable the preparation of bulk composites, heterostructures, and folded or crumpled sheets with unique properties and applications. This talk will review the current state-of-the art in the exfoliation and re-assembly of different classes of 2D materials.

Hybrid Growth Approaches and Hybrid Materials Options: Unconventional Opportunities Available in the 2DCC-MIP

Thursday, March 30, 2017

Speaker: Roman Engel-Herbert
Description: This webinar will describe a specific thin film growth capability available in the 2DCC-MIP that combines MBE and MOCVD in a unique way as well as opportunities to users to integrate 2D chalcogenides with functional oxide materials.

Bulk Crystal Growth of Chalcogenides at the 2DCC

Thursday, February 23, 2017

Speaker: Dr. David Snyder
Description: This webinar will describe the capabilities and equipment being established at the 2DCC to synthesize and characterize high quality bulk crystals for a range of chalcogenides. Emphasis will be placed on building a capability for investigations of equilibrium growth of alloys and doped crystals, comparison of exfoliated bulk materials with CVD/MBE films, synthesis of new phases/compositions of 2D crystals and providing unique bulk crystals as substrates.

Defects in Two Dimensional Layered Crystals: An Ultra-High Resolution Aberration-Corrected Electron Microscopy Study

Thursday, January 26, 2017

Speaker: Nasim Alem
Description: This webinar will explore ultra-high resolution aberration-corrected electron microscopy to investigate the chemical and atomic nature of the interfaces, defects and grain boundaries in atomically thin 2D crystals, i.e. graphene, hexagonal boron nitride, and the transition metal dichalcogenides, and their heterostructures.
