PROBLEM TO BE SOLVED: To obtain a rod-like single crystal having a tip as sharpened as in an atomic level.;SOLUTION: A single crystal tungsten emitter, for example, is treated as follows. First, when a treatment voltage Vr is gradually increased at a high temperature (Tr=2,300°K), a field emission voltage Vext suddenly decreases just after a stage (D) and a 111 top is surrounded by (110) planes. Then the treatment process temperature is gradually lowered to Tr=1,700°K while keeping the voltage. Then, a thermal field treatment by a remolding method is continued while the temperature Tr is kept as low as 1,700°K; and when the FE pattern shows emission of electrons from several atoms at the tip, the treatment is stopped.;COPYRIGHT: (C)2009,JPO&INPIT
