Description:About the Seminar:\n\nPlasmonic nanostructures have long been a
 ppreciated for their ability to harvest light and transform it into other 
 forms\, including thermal energy and chemical energy (through the producti
 on of high energy charge carriers\, e.g. hot electrons and hot holes). Bot
 h hot charge carriers and elevated temperatures at nanoparticle surfaces c
 an increase the efficiency of light-driven electrochemical reactions\, yet
  untangling the relative contributions of these two effects is experimenta
 lly challenging. This talk will describe our work to isolate local heating
  effects from hot carrier effects as well as provide quantitative values f
 or hot carrier energies using scanning electrochemical microscopy (SECM) o
 n gold nanoparticles at semiconductor interfaces. We generate real tempera
 ture values as well as effective hot carrier temperatures\, allowing us to
  understand how plasmon excitation promotes reactions on plasmon substrate
