Tuning the Critical Temperature of Ceprate Superconductor Films with Self-Assembled Organic Layers

摘要

Many of the electronic properties of high-temperature cuprate superconductors (HTSC) are strongly dependent on the number of charge carriers put into the CuO2 planes (doping). Superconductivity appears over a dome-shaped region of the doping-temperature phase diagram. The highest critical temperature (T_c) is obtained for the so-called "optimum doping". The doping mechanism is usually chemical; it can be done by cationic substitution.
