  Straintronics in two-dimensional materials

  Department of Electrical and Computer Engineering (ECE)

  10:30 AM L440, Technological Institute

  EVENT DETAILS

  The ECE and ME departments will be hosting a seminar, "Straintronics in two-dimensional materials" with Prof. Arend M. van der Zande from the University of Illnois Urbana-Champaign.

  Abstract: Recently, strain and deformation has emerged as a means to control material and device properties on an unprecedented scale. Two-dimensional (2D) materials are ideal “ultra-strength” systems for tuning properties via strain: they host rich strain-induced quantum behavior, while the lower dimensionality enables new kinds of deformations and high fracture strength. However, in many next generation technologies, from heterogeneous integration of 2D materials with CMOS processes, to wearable electronics, and quantum systems, strain is an important yet unknown or uncontrolled parameter. First, we utilize atomic to micro scale imaging to unravel the breakdown of continuum mechanics and new scaling laws in the atomic limit, and their influence on the electronic properties of 2D materials. For example, we demonstrate designable strain using thin film stressors to spatially pattern the electronic structure of 2D materials. Additionally, we image the nanoscale shape of bends in 2D heterostructures and discover the scaling laws that define interlayer slip at van der Waals interfaces, enabling membranes orders of magnitude more deformable than conventional thin films. We then leverage these fundamental insights to apply strain and deformation engineering across a broad range of applications such as mobility enhancement in 2D transistors, stretchable electronics, biosensors, and reconfigurable nanoelectromechanical systems.

  Arend M. van der Zande is an Associate Professor in Mechanical Science and Engineering at University of Illinois at Urbana-Champaign, with affiliations in Electrical and Computer Engineering, Materials Science, Materials Research Lab, and the Holonyak Micro and Nanotechnology Lab. He is a team lead on the Illinois Material Research Science and Engineering Center and was recently awarded the 2022 Society of Engineering Science Young Investigator Medal, the NSF CAREER award, and is on the Clarivate Analytics list of the world’s most influential researchers in 2018-2022. He earned a Ph.D. in Physics from Cornell University in 2011 and a B.S in Physics and Mathematics from University of California, Santa Cruz in 2003. He then became a postdoctoral fellow in the Department of Mechanical Engineering and the Energy Frontier Research Center at Columbia University. He has published 65+ articles with >23,000 citations in journals including Nature, Science, Nature Materials, Advanced Materials, and Nano Letters.

  ECE Distinguished Seminar - Joshua Goldberger

  Department of Electrical and Computer Engineering (ECE)

  2:00 PM L440, Technological Institute

  EVENT DETAILS

  Almost all electronic materials generally exhibit a majority carrier type, either electrons or holes, that dominates the transport uniformly along all directions of the crystal. These p-type and n-type regions are then integrated together to separate and control the flow of charge to create virtually all modern electronic and energy harvesting devices. Here, we will describe our recent work in the synthesis, properties, and applications of materials that exhibit, simultaneously, either dominant n-type or p-type conduction depending on the direction of travel. We will establish the origin of this exotic behavior and the band structure design principles for creating new materials that with this axis-dependent conduction polarity. This understanding has led us to rapidly expand the number of materials that experimentally exhibit this behavior. Finally, we will show that the unique charge separation inherent in these materials can overcome limitations in existing electronic and energy-harvesting devices, leading to exciting new technologies.

  Extending Care: A Conversation about Conservation and Futurity

  Block Museum of Art

  6:00 PM Block Museum of Art, Mary and Leigh

  EVENT DETAILSmore info

  The Center for Scientific Studies in the Arts is a collaboration between the Art Institute of Chicago and materials science-related departments at Northwestern University to pursue objects-based and objects-inspired scientific research. Materials research benefits ongoing work in conservation, archaeology, art history, and curatorial scholarship.

  Learn how the Center uses materials research to care for art objects in sustainable, innovative ways with Maria Kokkori, Northwestern Associate Professor of Electrical and Computer Engineering and Senior Scientist in the Center for Scientific Studies in the Arts. She will be in conversation with Corey Byrnes, Northwestern Associate Professor of Chinese Culture and co-founder/co-director of the Environmental Humanities Workshop in Kaplan Humanities Center.

  This event is presented by the McCormick School of Engineering and Applied Science in conjunction with exhibition Actions for the Earth: Art, Care & Ecology.
