SUMMARY:VANADIUM DIOXIDE:  THE NEVER-ENDING STORY?
DESCRIPTION:Featuring Richard Haglund\, Vanderbilt University\nHosted by: R
	ichard Averitt\n\nPart of the Biophysics/Condensed Matter Seminar Series.\n
	\nAbstract: Since its discovery half a century ago\, the insulator-to-metal
	 transition in vanadium dioxide (VO2) has been an object of both scientific
	 and technological attention.  In the last decade\, that attention has
	 produced a roughly exponential growth in VO2-related publications.  O
	ur interest in VO2 at the micro- and nano-length and femtosecond time-scale
	s\, has been driven in part by potential applications\, most recently in us
	ing micron-size patches of VO2 as the switching element in silicon photonic
	 modulators. I will describe our most recent experiments focused on key sci
	entific issues related to the potential for making ultrafast optical modula
	tors with VO2 micro- and nanostructures\, including:  (1) using gold n
	anodisks as plasmonic antennas to probe the interband response during the i
	nsulator-to-metal transition; (2) femtosecond laser studies of near-thresho
	ld switching in the visible and near-infrared; and (3) plasmonically driven
	 ultrafast electron injection in nanostructured VO2.
