Passivity and passivity breakdown on copper: In situ and operando observation of surface oxides
TL;DR: In this paper, in situ spectroscopic ellipsometry was used to investigate the oxide growth and stability on copper, while the nature of oxides was studied through in situ Raman spectroscopy.

Suppression of superconductivity in high-Tc cuprates due to nonmagnetic impurities: Implications for the order parameter symmetry
Mehmet Bayindir,Zafer Gedik +1 more
TL;DR: In this article, the effects of nonmagnetic impurities on high-temperature superconductors were studied by solving the Bogoliubov-de Gennes equations on a two-dimensional lattice via exact diagonalization technique in a fully selfconsistent way.
Journal ArticleDOI
Magnetically modulated microwave absorption studies on high-Tc powdered materials
TL;DR: In this paper, a model that combines a model based on the existence of a critical state with pinning and depinning of fluxons during a modulation cycle and a weak link model, can account for the observed temperature and particle-size dependence of zero field line and hysteresis.
Journal ArticleDOI
Advantages of High- T c Cuprates over Semiconductors for Making Room Temperature Electronic Devices
TL;DR: In this article, the authors demonstrate that the high Tc cuprates in the pseudogap states have many advantages over the semiconductors for making room temperature electronic devices, and they predict that the Pseudo-Gap Body will replace the semiconductor in many applications.
