Surface structure of Fe)3)O)4)(110) studied byscanning tunneling microscopy

We have studied the (110) surface of magnetite Fe)3)O)4) with a UHV scanning tunneling microscope (STM). The surface was prepared by a combination of sputtering and annealing at 1200 K and shows straight terraces separated mainly by double and four-fold steps. On the terraces rows were found, with a...

Zusammenfassung:We have studied the (110) surface of magnetite Fe)3)O)4) with a UHV scanning tunneling microscope (STM). The surface was prepared by a combination of sputtering and annealing at 1200 K and shows straight terraces separated mainly by double and four-fold steps. On the terraces rows were found, with a separation of about 25 A. Current versus voltage characteristics measured on this surface display a gap in the conductivity of about 2 eV. Results will be discussed considering the bulk Fe)3)O)4 ) structure
