Size effect of nanometer vacuum gap thermionic power conversion device with CsI coated graphite electrodes

Cesium iodide (CsI) coated graphite is a good candidate for an electrode material of a thermionic power generation device due to its low work function. In this letter, a thermionic device with a nanometer-scale vacuum gap between a CsI coated graphite emitter and a collector will be investigated whi...
