WebA deflected edge emission field effect transistor (DEEFET), a hybrid solid-state and vacuum microelectronics device, was constructed with electron-beam lithography to measure magnetic fields. The fabricated DEEFET device employs an extremely sharp emitter tip, a pair of gate electrodes, and a pair of split anodes. WebIn the scanned near field, we resolved enhanced emission from patterned regions with high resolution images of emitting surface. Also NSOM in illumination mode was used for patterning of predefined structures on semiconductor surfaces. For the diode patterning the electron beam direct writing lithography was used.
