Mark Hersam

Professor of Materials Science and Engineering; Professor of Chemistry; Bette and Neison Harris Chair in Teaching Excellence; Director, Materials Research Science and Engineering (MRSEC)

Ph.D. in Electrical Engineering, University of Illinois at Urbana-Champaign, 2000; M.Phil. in Microelectronic Engineering and Semiconductor Physics, University of Cambridge (UK), 1997; B.S. in Electrical Engineering, University of Illinois at Urbana-Champaign, 1996

Research Interests

The Hersam Research Group specializes in the processing, characterization, and application of nanoelectronic materials including graphene, carbon nanotubes, and silicon.  Of specific interest are strategies for producing monodisperse nanomaterials and organically/biologically functionalizing semiconductor surfaces.  Experimental techniques range from atomic-resolution ultra-high vacuum scanning tunneling microscopy to macroscopic charge transport and optical property measurements.  A wide range of applications are being explored including integrated circuits, optoelectronic devices, biosensors, drug delivery, photovoltaics, catalysis, and batteries.
