Effect of Cr-doping on the electronic structure and work function of [small alpha]-Fe2O3 thin films

13-Sep-2017 | Xiaolong Li; Li Chen; Hongmei Liu; Zhishan Mi; Changmin Shi; Lijie Qiao, Physical Chemistry Chemical Physics, 2017

We investigate the effect of Cr-doping on the properties of α-Fe2O3 (001) thin films with Fe termination using the local density approximation plus a Hubbard U correction. We find that both the doping site and concentration of Cr atoms dramatically affect the electronic structure and work ...
