ABSTRACT
We demonstrate that the electron spin resonance–scanning tunneling microscope can detect the Larmor frequency of a single spin with the atomic scale resolution on the oxygen-adsorbed Si(111)-7×7 surface. The spin signal from the Si dangling bond was detected on the oxygen-induced bright Si adatom with the Larmor frequency corresponding to g∼2.00. However, no peak was detected on the dark adatom that is tied with an oxygen atom and the dangling bond is disappeared.

    By combining the spatial resolution of a scanning-tunneling microscope (STM) with the electronic spin sensitivity of electron-spin resonance, we show that it is possible to detect the presence of localized spins on surfaces. The principle is that a STM is operated in a magnetic field, and the...

    The authors use scanning tunneling microscopy to study the initial stage of oxidation for H2O exposed Si(100). Following H2O dissociation and saturation of the surface with Cl, a mild anneal allows the oxygen to insert into the Si dimer bonds. Bridge-bonded oxygen atoms appear as a dark spot in...
