SUMMARY:Low work function diamond surfaces - Kane O’Donnell\, Centre for
  Nanoscience and Quantum Information\, University of Bristol
DTSTART:20100506T150000Z
DTEND:20100506T160000Z
UID:TALK23830@talks.cam.ac.uk
CONTACT:Stephen Walley
DESCRIPTION:In this talk I will describe the efforts underway at Bristol t
 o produce a solar thermionic converter based on lithiated diamond nanopowd
 ers. In addition to outstanding mechanical properties\, diamond is a very 
 interesting electronic material and we have demonstrated very low threshol
 d field emission and low-temperature thermionic emission for reasons not e
 ntirely clear at this point. I will present ab-initio calculations suggest
 ing a lithium surface adsorbate role and describe our experimental efforts
  to investigate nanodiamond emitters.
