Abstract :
In this study, natural type lib diamond was used to characterise the origin of emitting electrons by the means of combined XPS/UPS/FES. Natural type lib diamond is one of the most intensively studied diamond due to its semiconductor properties and negative electron affinity (NEA) on hydrogenated (111) surface. The origin of emitting electrons from hydrogenated natural type lib diamond (111) surface, thus, can be a one of the most appropriate reference data for the future studies for diamond with various dopants and various surface terminations.
