Research Abstract |
I have developed a UHV chamber equipped with apparatus for observing both FIM and FEM images, that enables us to characterize novel spin-polarized-electron emitter with single atom dimension. By executing a remolding treatment, i.e. thermal field processing, on blunt W tips, I have fabricated electron beam sources consisting of approximately a dozen of atoms, or, at largest, a few. I have neither deposited magnetic atoms, nor started the spin-polarization measurement yet.
