Sen'i Gakkaishi, 1988 Publisher Summary Scanning tunneling microscopy (STM) has been finding ever increasing application in surface physics. STM, even as it is used now, has furnished fascinating results, and undoubtedly, holds the greatest promise for surface physics. This is because of its unique resolution that can approach hundreds of angstroms along the normal to the
