Dizayee, W., Ying, M., Griffin, J. et al. (4 more authors) (2018) Investigation of the distribution of localised and extended states in amorphous MoOx. AIP ADVANCES, 8 (5). 055118. ISSN 2158-3226
Abstract
Amorphous films of MoOx have both structural disorder and also chemical disorder for x<3. We have shown that this disorder can introduce localised states in thin films and have shown that the existence of localised states can be deduced from the XPS data that identifies the relevant occupations of different ionisation states of the Mo ions. This effect, which depends on both the oxygen concentration and the method of fabrication, is more important than electron-electron interactions in producing the observed localisation. We have also shown that magneto-optical dichroism is also a powerful technique to determine the energy distribution of localised and delocalised states.
