Title: Scan type tunnel electron microscope
Inventor: ISHIBASHI AKIRA
IPC: G01B7/34
Filed: 1990-05-31
Abstract: PURPOSE:To measure not only electron energy on the surface of a substance but their momentum with a high resolution by usinga probe in the form of a plate and having a sharp appex. CONSTITUTION:As a probe 1 is asymmetrical about its own axis, the shape of t region 3 where a tunnel current flows between the tip of this probe 1 and the surface of a specimen 2 becomes also asymmetrical about the axis of the probe 1. Consequently electrons on the surface of the specimen 2 will have a large momentum in the direction vertical to the plate surface of the probe 1. Accordingly the momentum of the electrons on the surface of substance can be obtained by rotating the probe 1 round its own axis and varying the angle formed by the direction in parallel with the plate surface of probe 1 to a certain reference direction vertical to the probe axis.

Abstract: PURPOSE:To stabilize the outputs of a collector power source and a helix addition power source and improve the load alteration of the collector power source by overlaying the outputs of a collector power source and a helix addition power source. CONSTITUTION:AC voltage is filtered by a rectifying circuit 1 and supplied to a control circuit 2 and high voltage generating circuit 3. The control circuit 2 generates voltage which controls the heater power source 4 and the high voltage generating circuit 3. The high voltage generating circuit 3 transforms the voltage of the rectifying circuit 1 into high frequecy voltage and supplies it to a collector power source 5 and a helix addition power source 6. The collector power source 5 transforms the voltage from the high voltage generating circuit 3 into high frequency voltage and supplies it to the collector power source and helix addition power source 6. The collector power source 5 raises, rectifies, and filters the voltage of the high voltage generating circuit 3 and applies it to a cathode electrode 7 and a collector electrode 8. A detection circuit 10 detects the voltage between both electrodes and returns to the high voltage generating circuit 3 and stabilizes the helix voltage. Since if the collector power source decreases, the helix voltage also decreases, both power sources 5, 6 incline to increase outputs and the alteration of the output voltage decreases.
