The coexistence of gamma(gamma') and theta alumina observed by STM and LEED on top of oxide layer grown on CoAl(100)
We report the coexistence of gamma(gamma') and theta alumina grown on the CoAl(l 0 0) surface. Both phases were observed after annealing of alumina at 1150 K by means of scanning tunnelling microscopy (STM). The crystal structures of gamma(gamma') and 0 alumina were indexed based on low energy electron diffraction (LEED) and STM experimental data. (c) 2005 Elsevier B.V. All rights reserved.
