Abstract
In this talk I will describe the efforts underway at Bristol to produce a solar thermionic converter based on lithiated diamond nanopowders. In addition to outstanding mechanical properties, diamond is a very interesting electronic material and we have demonstrated very low threshold field emission and low-temperature thermionic emission for reasons not entirely clear at this point. I will present ab-initio calculations suggesting a lithium surface adsorbate role and describe our experimental efforts to investigate nanodiamond emitters.
Series This talk is part of the Physics and Chemistry of Solids Group series.
