December 5 Live Webinar: 2DCC Webinars: Magnetic Switching with Topical Insulator and Compensated Ferrimagnet

New materials and physics mechanisms are required to further lower down the power consumption and increase the switching speed of spintronic devices. In this talk, I will focus on two novel material systems which can provide superior performances for magnetic switching: topological insulators, whose spin orbit interaction can lead to efficient room temperature magnetic switching in a topological insulator/ferromagnetic heterostructure; and ferrimagnet, where the antiferromagnetically coupled spin textures can enable spintronic devices with fast speed and high density.

November 5 Live Webinar: 2DCC Webinars: Topological Valleytronics in Bilayer Graphene

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.

October 3 Live Webinar: 2DCC Webinars: Atomic Force Scanning Tunneling Microscopy

In this talk I will introduce a variety of atomic force (AFM) and scanning tunneling microscopy (STM) measurement techniques for atomic scale investigations of the structural and electronic properties of materials, with examples drawn primarily from investigations of 2D material systems.

May 30 Live Webinar: 2DCC Webinars: Intercalation, Exfoliation, Assembly of 2D Materials

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.

February 23 Live Webinar: Bulk Crystal Growth of Chalcogenides at the 2DCC

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.

January 26, 2017 Live Webinar: Defects in Two Dimensional Layered Crystals: An Ultra-High Resolution Aberration-Corrected Electron Microscopy Study

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.

November 29, 2016 Live Webinar: The Science of Inclusion

This talk presents social psychological research demonstrating how subtle cues in social environments can inadvertently signal exclusion to members of underrepresented groups. It will focus on the power of psychological interpretations of environments and how these can satisfy or thwart basic psychological needs with implications for student motivation and persistence.
