    Mixed-Dimensional van der Waals Heterostructures for Electronic and Energy Applications


    Mark C. Hersam

    2018 Kay Malmstrom Lecture in Physics

    Guest Lecturer: Mark C. Hersam, PhD
    Walter P. Murphy Professor of Materials Science and Engineering and director of the Materials Research Center at Northwestern University

    Layered two-dimensional (2D) nanomaterials interact primarily via van der Waals bonding, which has created new opportunities for heterostructures that are not constrained by epitaxial growth. However, it is important to acknowledge that van der Waals interactions are not limited to interplanar interactions in 2D materials. In principle, any passivated, dangling bond-free surface interacts with another via non-covalent forces. Consequently, the emerging layered 2D nanomaterials can be integrated with a diverse range of other materials, including those of different dimensionality, to form van der Waals heterostructures. This talk will explore mixed-dimensional combinations of 2D + n-D (n = 0, 1 and 3) materials, thus significantly expanding the van der Waals heterostructure concept. In addition, it will explore several fundamental issues, including band alignment, doping, trap states, and charge/energy transfer across previously unexplored mixed-dimensional heterointerfaces.

  • About the Malmstrom Lectures in Physics

    The Kay Malmstrom Lecture in Physics, part of the Emma K. and Carl R. N. Malstrom Chair in Physics, is an annual symposium on contemporary issues and research in physics. Through this generous gift, Carl R. N. Malmstrom ’36 gives Hamline students access to the outstanding scientific minds of our time. Even after his death in 2010, Carl’s legacy of supporting Hamline students continues to fund collaborative research opportunities, scholarships, and this lecture.
