“…21), and the Hall anomaly can be tuned by the EDLT method. Compared with traditional chemical substitutions, the tuning of carrier concentration by electrostatic doping will not bring more disorder or pinning centers into the system [152]. Thus, such double sign reversal urges the consideration of two band feature in mixed state [153].…”

Superconductivity research is like running a marathon. Three decades after the discovery of high-T c cuprates, there have been mass data generated from transport measurements, which bring fruitful information. In this review, we give a brief summary of the intriguing phenomena reported in electron-doped cuprates from the aspect of electrical transport as well as the complementary thermal transport. We attempt to sort out common features of the electron-doped family, e.g. the strange metal, negative magnetoresistance, multiple sign reversals of Hall in mixed state, abnormal Nernst signal, complex quantum criticality. Most of them have been challenging the existing theories, nevertheless, a unified diagram certainly helps to approach the nature of electron-doped cuprates.2
