We will report on the field emission properties of single crystal n-type cubic boron nitride (c-BN) for the first time. Vacuum annealed positive electron affinity (PEA) surface shows lower threshold voltages compared to H-terminated negative electron affinity (NEA) surface. An internal barrier height of c-BN surface with NEA was estimated to be 3.5 eV according to the Schottky barrier lowering model,...
Field emission properties of nitrogen(N)-doped diamond with different dopant concentrations were investigated. Time-of-flight secondary ion mass spectroscopy measurement on the diamond samples showed a correlation between threshold field and the intensity of carbon(C)-nitrogen(N). This suggests that the N incorporation in the form of C-N, may be responsible for the extremely low threshold emission...
Field emission properties from 2D-hole accumulation layers on H-terminated undoped intrinsic CVD diamonds were measured. We also measured field emission properties of pand n-type semiconducting diamonds with H-terminations. Plateau in field emission properties of undoped intrinsic diamond were observed, while no pand n-type diamonds showed continuous increase of emission currents. It was considered...
We have been focusing on fabricating a photodetector that consists of a diamond cold cathode and an amorphous selenium (a-Se) photoconductor, which is one of the practical applications of a cold cathode. We have previously succeeded in achieving a proto-type photodetector of which a heavily nitrogen (N)-doped diamond was used as the cold cathode, and the results indeed showed a low operation voltage...
The study aims to investigate the energy band diagram of emitting diamond using the electron energy distribution obtained from combined X-ray photoelectron spectroscopy, ultraviolet photoelectron spectroscopy, and field emission spectroscopy. Combination of UPS and FES can determine the origin of electron field emission relative to the electronic structure of diamond. By adding XPS, the origin of...
