Electronic structure of paramagnetic transition metal complexes
Published 2017“…In Chapter 3, we address the question of redox-dependent spin transitions in triangular iron complexes. Experiments have shown that one-electron reduction of a pyrazolate-bridged Fe<sup>III</sup><sub>3</sub> cluster drives a transition from high- to low-spin configurations at all three metal centres. …”

Valley-optical absorption in planar transition metal dichalcogenide superlattices
Published 2023“…By calculating the effective mass for different bands and using the Drude-Lorentz model, our approach is able to determine the oscillator strength and the effective refractive index of the structure. We found that the spin-orbit coupling has important effect on the absorption coefficient and energy bands where it reduces the absorption coefficient of the structure from typical value of [Formula: see text]-[Formula: see text], also the valence band experiences a significant blue shift, while the conduction band shows minor changes due to spin orbit coupling. …”
