Research Abstract

We have studied the quantum tunneling phenomena that are the basic research of developing SP-STM.Our SP-STM can observe micro magnetic states of surfaces without an affection of the tip.
(1) We succeeded in observing the spin polarized tunneling current between GaAs sample and Ni tip by STM in 1992.
(2) The UHV-STM system has been developed and it becomes clear that the tunneling current depends on the polarity of the incident light to the GaAs sample and the magnetization of the Ni tip. A photovoltaic effect was observed and STS was measured, so we can understand the energy band structure and spin polarization of these materials.
(3) We are also developing a quantum well structure, a technology of processing to the tip by FIB and Mott spin analyzer.
