Cleavage burble device null for scanning-type tunnel microscope

摘要

PURPOSE: To easily and surely perform a process of cleaving/separating a sample even under the observational atmosphere, even in a general use small sized scanning type tunneling microscope, by combining a sample pressing member, guide member, elastic member and a fixed member so as to perform specific action. ;CONSTITUTION: A sample 1 is firmly mounted on a sample holder 2, to insert this sample holder 2 fitted to a sample stage 3. The inside of a scanning type tunneling microscope is replaced with the inert gas atmosphere. Next by operating sample stage driving micrometers 8, 9, the sample stage 3 is slid toward a direction of a fixed member 7. Then in a certain part, one end part A of a sample pressing member is brought into contact with the fixed member 7. In a certain part, the other end part of the sample pressing member 4 is brought into contact with the sample 1, but when the sample stage 3 is further moved, pressing force with an edge of the sample holder 2 serving as the supporting point (working point) is applied to the sample 1. Finally the sample 1 is cut down (cleft) by the sample pressing member 4.;COPYRIGHT: (C)1995,JPO
