Study using field ion microscope (1)Measuring field emission current and field ion current of Ir covered single atom tip (2)Direct observations of Nb(100) surfaces
碩士 === 國立臺灣師範大學 === 物理學系 === 100 === Using Fraday cup and MCP (microchannel plate) measured field emission currents and field ion currents after Ir covered single crystal tungsten tips form pyramid strcture. Tip’s shape affects field emission current more then pyramid strcture. Threshold voltage...
