Highlights

a) Schematic of 2D heterostructure bent over a hexagonal boron nitride (h-BN) step. b-c) Scanning transmission electron microscopy images of graphene-MoS2 heterostructures over h-BN steps. The bending stiffness is measured from the shape of the bend in the image. Scale bars are 2 nm. d) Experimental bending stiffness of four-layer graphene-MoS2 heterostructures with different stacking orders. By simply changing the order of the graphene and MoS2 layers, the bending stiffness is tuned up to 400%.

Designing Highly Deformable 2D Materials and Heterostructures

A. M. van der Zande, P. Y. Huang, and E. Ertekin, University of Illinois at Urbana-Champaign
The Illinois MRSEC team has demonstrated a new ability to create ultra-soft 2D heterostructures by design. With combined electron microscopy studies and atomistic simulations, they show that systematically incorporating low-friction interfacial layers into 2D stacks tunes the bending stiffness up to several hundred percent.

Assembly of Linked Nanocrystal Colloids by Reversible Covalent Bonds

D. Milliron, E. Anslyn, T. Truskett: Univ. of Texas at Austin
This highlight demonstrates the combination of colloidal nanocrystals with uniquely developed ligands for the use of gelation assembly. Through this combined experimental, computational and theoretical work provided a platform for controlling and designing the properties of reversible colloidal assemblies.

Collective Excitations in Twisted Bilayers

X. Li, A. MacDonald, K. Lai, C. K. Shih: Univ. of Texas at Austin
Moire superlattices consist of two monolayers of atomically thin materials, in this case the transition metal dichalcogenide MoS2, stacked on top of each other with a slight rotational misalignment (twist) that creates a moire interference pattern between the atomic lattices of the two monolayers.

UC Santa Barbara MRSEC Continues REU Program Through COVID-19 Lockdown
The UC Santa Barbara ran a fully remote REU program in Summer 2020, with 18 students working on primarily computational projects. 18 students participated from 8 different colleges and universities. In addition to research, students participated in weekly intern group meetings, and weekly Zoom career building workshops, including Tips on Talks, Figures for Presentations, Poster Making, Finding Positions in Industry, Graduate School Panel, and others. All students presented their results in a virtual Summer Intern Colloquium.

Big Idea: Future of Work at the Human-Technology Frontier, Materials Under Extreme Conditions

Tiny Robots with Giant Potential (TED Talk)
Take a trip down the microworld as roboticists Paul McEuen and Marc Miskin explain how they design and mass-produce microrobots the size of a single cell, powered by atomically thin legs -- and show how these machines could one day be "piloted" to battle crop diseases or study your brain at the level of individual neurons.

Voltage Control of Magnetism above Room Temperature in epitaxial SrCo1-xFexO3-δ

Caroline A. Ross
Searching for new materials and phenomena to enable voltage control of magnetism and magnetic properties holds compelling interest for the development of low-power non-volatile memory devices. Here, we report on a non-volatile ON/OFF voltage control of magnetism in thin films of an oxide, SrCo1-xFexO3-δ (SCFO).
