Direct reaction of herringbone, platelet, or narrow, tubular herringbone graphitic carbon nanofibers (GCNFs) with molten potassium gives K/GCNF intercalates with stoichiometric control of potassium loading. Intercalate formation is confirmed by powder X-ray diffraction and micro-Raman spectroscopy. K/GCNF intercalates act as radical-anion alkene polymerization catalysts and reduce water with st...
The metal-insulator-semiconductor (MIS) diode is the most useful device in the study of semiconductor surfaces. The current-voltage data of the metal-insulatorsemiconductor Schottky diode are simulated using thermionic emission diffusion equation taking into account the interfacial layer parameters. The calculated current–voltage data are fitted into ideal thermionic emission diffusion equation...
Thermionic energy conversion, a process that allows direct transformation of thermal to electrical energy, presents a means of efficient electrical power generation as the hot and cold side of the corresponding heat engine are separated by a vacuum gap. Conversion efficiencies approaching those of the Carnot cycle are possible if material parameters of the active elements at the converter, i.e....
