Title: Development of liquid-metal-ion source low-energy ion gun/high-temperature ultrahigh vacuum scanning tunneling microscope combined system

Abstract

A liquid-metal-ion source low-energy ion gun/high-temperature ultrahigh vacuum scanning tunneling microscope combined system (LMIS-IG/STM) has been developed in order to investigate the ion beam modification process in situ based on our previous ion gun/STM combined system (IG/STM). Various kinds of metal ions can be irradiated with low acceleration energy of 0.01-5 keV during STM observation at 400-600 deg. C. As an example, real-time STM observation of Si(111)7x7 surface irradiated with Si{sup 2+} ions is demonstrated. The STM results have shown that the surface defects generated by Si{sup 2+} ion irradiation exhibit similar behavior of surface defects induced by Ar{sup +} irradiation with IG/STM.
