Flannigan awarded NSF CAREER grant

Nov. 17, 2016 - Assistant Professor David Flannigan has been awarded a Faculty Early Career Development (CAREER) award from the National Science Foundation (NSF) to support his research on "Defect-Modulated Energy Transport in Semiconducting Materials." This prestigious award provides support of junior faculty who exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research within the context of the mission of their organizations.

With this grant, Flannigan plans to study ultrafast atomic-scale mechanisms of energy transport and conversion in semiconducting materials, especially in the presence of discrete imperfections in atomic and nanoscale ordering. He will do this through direct-imaging studies, with ultrafast electron microscopy, of laser-excited energy nucleation, conversion, propagation, and decay over distances spanning one billionth of a meter and on timescales as short as one millionth of a billionth of a second. One of the major goals is to develop a detailed understanding of how material imperfections affect processes associated with electron excitation, scattering, coupling to the crystal lattice, and subsequent evolution of atomic motion over time. Closely integrated with this will be education and outreach activities focused on introducing underrepresented students to the importance of materials and methods for characterizing their properties. Flannigan will accomplish this through the establishment of the Minnesota Electron Microscopy Summer School (MEMS^2) and through industrial collaborations.
