Malmstrom Lecture to Examine Materials of Tomorrow


The future of technology and energy production will be under consideration on Friday, November 9 as Hamline University’s physics department hosts the 27th Annual Kay Malmstrom Lecture in Physics at Sundin Music Hall.

The Malmstrom Lecture is an annual symposium on contemporary issues and research in physics, applied physics, and related fields. More than 120 guests are expected.

Since the inaugural event in 1991, which coincided with the dedication of the Robbins Science Center, the Malmstrom Lecture has spanned the field of physics with guests addressing topics as diverse as quarks, quantum liquids, astronomy, time and even, the television show Star Trek.

This year, Mark C. Hersam, the Walter P. Murphy Professor of Materials Science and Engineering and the Director of the Materials Research Center at Northwestern University, will give a talk titled, “Mixed-Dimensional van der Waals Heterostructures for Electronic and Energy Applications.”

Van der Waals heterostructures have broad applications, including, but not limited to electronic (i.e., digital logic circuits, anti-ambipolar transistors, neuromorphic memtransistors, photodetectors, light-emitting devices (LED)), energy (i.e., lithium-ion batteries, solar cells, capacitors), and biomedical (i.e., biosensor, medical imaging, drug delivery) applications.

“The talk will introduce mixed-dimensional van der Waals heterostructures and their potential electronic and energy applications, and address several fundamental issues including band alignment, doping trap states, and charge and energy transfer,” said Professor and Physics Department Chair Lifeng Dong.

The design, synthesis, and structural characterizations of mixed-dimensional Van der Waals heterostructures will provide opportunities for the development of next generation electronic and energy devices.

The Hamline University Renewable Energy and Environmental Research (REER) Laboratory has worked with collaborators and students to design, synthesize/fabricate, and characterize these and similar applications, so the talk is timely for the campus as well as the larger physics community.

“Importantly, Hersam will share with the students how interdisciplinary education and collaboration are critical important for developing the next generation electronic and energy devices,” added Dong.

Over the last 26 years, Hamline has hosted nine Nobel Prize Laureates in Physics for the Malmstrom Lecture and is fortunate to have Dr. Hersam on campus for 2018. He is a highly respected researcher who has received several honors including the Presidential Early Career Award for Scientists and Engineers, TMS Robert Lansing Hardy Award, AVS Peter Mark Award, MRS Outstanding Young Investigator, U.S. Science Envoy, and MacArthur Fellowship.

Dr. Hersam is the co-founder of NanoIntegris, which is a commercial supplier of nanoelectronic materials, and an elected member of the National Academy of Inventors. He is a fellow of Materials Research Society (MRS), American Vacuum Society (AVS), American Physical Society (APS), American Association for the Advancement of Science (AAAS), Society of Photo-Optical Instrumentation Engineers (SPIE), and Institute of Electrical and Electronics Engineers (IEEE), and also serves as an Associate Editor of ACS Nano.

About the Malmstrom Lectures in Physics
The Kay Malmstrom Lecture in Physics, part of the Emma K. and Carl R. N. Malmstrom 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.
