Research Abstract

I developed the scanning tunneling microscope (STM) holder which can be installed in an ultrahigh vacuum transmission electron microscope (TEM) under liquid nitrogen cooling temperature. Using this holder, I fabricated the gap of the nanometer level by milling by the convergence ion beam irradiation and deposited highly-pure magnetic metal around the gap by a micro deposition source and performed the electric conductance measurement of during observing the structure under liquid nitrogen cooling in TEM.
