4. INVESTIGATION OF METAL-INSULATOR TRANSITION Figure 4.20: Nickel 2p multiplet spectrum fitting at for sample S-30AOn - A distinct splitting of 2p3/2 envelope is evident at low temperature, this splitting disappears in the course of heating. the absolute values of line positions are not discussed here. However, the obtained fitting results still hold value for comparison of spectra for various temperatures and samples when comparing energy displacement between individual constituent lines (that are probably groups of peaks) as well as peak area ratios. The men- tioned parameters when compared with respect to temperature or sample thick- ness have provided ground to draw conclusions of variation of electronic structure across investigated metal-insulator transition. Nickel spectra collected for samarium nickelate thin films present subtle changes with respect to temperature. In-depth analysis of two constituent lines of main part of Ni 2p multiplet, that is Ni 2p3/2 line, revealed transfer of spectral weight between the two lines but more importantly a temperature dependent variation of energy difference between them. For each annealed SmNiO3 thin film a general trend is that the energy difference between the two peaks decreases while tem- perature increases. What is more, for thinner films the energy difference is larger in comparison with respective spectra for films with greater thickness, regardless of temperature. 114PDF Image | Investigation of metal-insulator transition in magnetron sputtered samarium nickelate thin films
