  • proximity induced High Temperature Superconductivity in the topological insulators bi 2 se 3 and bi 2 te 3
    Nature Communications, 2012
    Co-Authors: Parisa Zareapour, Alex Hayat, Shu Yang Frank Zhao, Michael Kreshchuk, Achint Jain, Daniel C Kwok, Nara Lee, Sangwook Cheong, Alina Yang, Shuang Jia
    Abstract:

    Interest in the superconducting proximity effect has been reinvigorated recently by novel optoelectronic applications as well as by the possible emergence of the elusive Majorana fermion at the interface between topological insulators and superconductors. Here we produce High-Temperature Superconductivity in Bi(2)Se(3) and Bi(2)Te(3) via proximity to Bi(2)Sr(2)CaCu(2)O(8+δ), to access Higher Temperature and energy scales for this phenomenon. This was achieved by a new mechanical bonding technique that we developed, enabling the fabrication of High-quality junctions between materials, unobtainable by conventional approaches. We observe proximity-induced Superconductivity in Bi(2)Se(3) and Bi(2)Te(3) persisting up to at least 80 K-a Temperature an order of magnitude Higher than any previous observations. Moreover, the induced superconducting gap in our devices reaches values of 10 mV, significantly enhancing the relevant energy scales. Our results open new directions for fundamental studies in condensed matter physics and enable a wide range of applications in spintronics and quantum computing.

  • High Temperature Superconductivity in monolayer bi 2 sr 2 cacu 2 o 8 δ
    Nature, 2019
    Co-Authors: Peng Cai, Ruidan Zhong, Jian Shen, X H Chen, Yuanbo Zhang
    Abstract:

    Although copper oxide High-Temperature superconductors constitute a complex and diverse material family, they all share a layered lattice structure. This curious fact prompts the question of whether High-Temperature Superconductivity can exist in an isolated monolayer of copper oxide, and if so, whether the two-dimensional Superconductivity and various related phenomena differ from those of their three-dimensional counterparts. The answers may provide insights into the role of dimensionality in High-Temperature Superconductivity. Here we develop a fabrication process that obtains intrinsic monolayer crystals of the High-Temperature superconductor Bi2Sr2CaCu2O8+δ (Bi-2212; here, a monolayer refers to a half unit cell that contains two CuO2 planes). The Highest superconducting transition Temperature of the monolayer is as High as that of optimally doped bulk. The lack of dimensionality effect on the transition Temperature defies expectations from the Mermin–Wagner theorem, in contrast to the much-reduced transition Temperature in conventional two-dimensional superconductors such as NbSe2. The properties of monolayer Bi-2212 become extremely tunable; our survey of Superconductivity, the pseudogap, charge order and the Mott state at various doping concentrations reveals that the phases are indistinguishable from those in the bulk. Monolayer Bi-2212 therefore displays all the fundamental physics of High-Temperature Superconductivity. Our results establish monolayer copper oxides as a platform for studying High-Temperature Superconductivity and other strongly correlated phenomena in two dimensions. Transport and scanning tunnelling microscopy studies of freestanding monolayers of an unconventional layered copper oxide establish that the superconducting properties of copper oxides are not changed in the 2D limit.

  • evolution of High Temperature Superconductivity from a low t_ c phase tuned by carrier concentration in fese thin flakes
    Physical Review Letters, 2016
    Co-Authors: B Lei, J H Cui, Z J Xiang, C Shang, N Z Wang, X G Luo, Zhe Sun, X H Chen
    Abstract:

    We report the evolution of Superconductivity in an FeSe thin flake with systematically regulated carrier concentrations by the liquid-gating technique. With electron doping tuned by the gate voltage, High-Temperature Superconductivity with an onset at 48 K can be achieved in an FeSe thin flake with T_{c} less than 10 K. This is the first time such High Temperature Superconductivity in FeSe is achieved without either an epitaxial interface or external pressure, and it definitely proves that the simple electron-doping process is able to induce High-Temperature Superconductivity with T_{c}^{onset} as High as 48 K in bulk FeSe. Intriguingly, our data also indicate that the Superconductivity is suddenly changed from a low-T_{c} phase to a High-T_{c} phase with a Lifshitz transition at a certain carrier concentration. These results help to build a unified picture to understand the High-Temperature Superconductivity among all FeSe-derived superconductors and shed light on the further pursuit of a Higher T_{c} in these materials.

    Abstract:

    We report the evolution of Superconductivity in an FeSe thin flake with systematically regulated carrier concentrations by the liquid-gating technique. With electron doping tuned by the gate voltage, High-Temperature Superconductivity with an onset at 48 K can be achieved in an FeSe thin flake with ${T}_{c}$ less than 10 K. This is the first time such High Temperature Superconductivity in FeSe is achieved without either an epitaxial interface or external pressure, and it definitely proves that the simple electron-doping process is able to induce High-Temperature Superconductivity with ${T}_{c}^{\text{onset}}$ as High as 48 K in bulk FeSe. Intriguingly, our data also indicate that the Superconductivity is suddenly changed from a low-${T}_{c}$ phase to a High-${T}_{c}$ phase with a Lifshitz transition at a certain carrier concentration. These results help to build a unified picture to understand the High-Temperature Superconductivity among all FeSe-derived superconductors and shed light on the further pursuit of a Higher ${T}_{c}$ in these materials.
