Photoemission electronic states of epitaxially grown magnetite films

Water Dissociation on Magnetite (001) Films

“…Also, for easier discussion later, one of the spots caused by the (√2 × √2)R45° is indicated by an arrow. The LEED pattern has been interpreted by different surface termination models with different methods of surface preparation. ,− In the present work, the method of films preparation is similar to that reported with the modified B termination . To distinguish between A and B terminations, one also can use Auger signal ratio of O to Fe.…”

“…To distinguish between A and B terminations, one also can use Auger signal ratio of O to Fe. It was reported that for the B termination the ratio is 3.34(5) and for the A termination it is 2.96(5). , On the basis of our AES data, the ratio is 3.61, which indicates that the films we prepared are of the B termination. Moreover, our UPS gives a W F of 5.45 eV, which is also consistent with the value of the B termination (5.32 eV, 5.20 ± 0.15 eV). , Thus, we confirm that the films we prepared are of the modified B termination.…”
