studied based on a mean-field theory of the doped Mott insulator, where the underlying …

Reversible band structure engineering in semimetal SrIrO3 films using atomic hydrogen

W Sun, W Guo, J Yang, R Liu, Y Li, C Gu, Z Gu… - Applied Physics …, 2022 - pubs.aip.org
We report on the atomic hydrogen annealing to in situ manipulate the electronic structures in
semimetal SrIrO 3 films. Carriers are found to be effectively doped into epitaxial SrIrO 3 films …

Phenomenological single-particle Green's function for the pseudogap and superconducting phases of high- cuprates

As a typical hole-doped cuprate superconductor, Bi 2 Sr 2 CaCu 2 O 8+ δ (Bi2212) carrier
doping is mostly determined by its oxygen content. Traditional doping methods can regulate …

Application of the pseudo-Voigt function to the analysis of single-particle tunneling spectra of d-wave superconductors

OK Ganiev - Physica C: Superconductivity and its Applications, 2023 - Elsevier
In this study, we focused on the peak–dip–hump structure, which is a hallmark of cuprate
superconductivity and is often used to explore the relationship between strong electron …
