Plasmons and high-temperature superconductivity

Physical Review B, 1989
Long-wavelength charge fluctuation models are constructed for 1:2:3 superconductors. These include planar plasmons (..omega..approx. ..sqrt..q ) plus numerous acoustical plasmons (..omega..approx.q). We show that these modes do not cause pairing of electrons into a superconductor state.

High temperature superconductivity

Journal of Polymer Science Part C: Polymer Symposia, 1970
AbstractThe critical temperature, Tc, for all presently known superconductors does not exceed 21'K. This fact obviously limits the range of applications of superconductivity in technology in a very fundamental way. On the whole, the reason why the value of Tc for “ordinary” superconductors would not exceed 20‐40oK is fairly well understood. At the same

High Temperature Superconducting Oxide Films

IEEE Transactions on Components, Hybrids, and Manufacturing Technology, 1988
The authors used sputter deposition with single oxide targets and metal molecular beam epitaxy to prepare thin films of the high-T/sub c/ oxide Y-Ba-Cu-O superconductor. The processing parameters, the structural characteristics, and the transport properties of the films are reported. The authors also discuss the microstructures of superconducting Y/sub

The problem of high temperature superconductivity

Contemporary Physics, 1968
Abstract The critical temperature, T c, for all presently known superconductors does not exceed 20°K. This fact obviously limits the range of applications of superconductivity in technology in a very fundamental way. On the whole, the reason why the value of T c for ‘ordinary’ superconductors should not exceed 20–40 °K is fairly well understood on the ...

Theory of high-temperature superconductivity

Physical Review B, 1988
A theory for high-temperature superconductivity is developed based on a hydrodynamic approximation to the many-body problem. Electrons confined to two-dimensional sheets exchange coupled two-dimensional plasmon and phonon modes. This leads to a strong electron-electron attraction. Bardeen-Cooper-Schrieffer theory is used to derive an expression for the

High Temperature Superconductivity

Physics World, 1996
The discovery of superconductivity at 93 °K in early 1987 represents one of the most exciting developments in modern physics. I shall first describe some events in the long search for superconductors with a high transition temperature (Tc) before 1986 that are important to later progress in high temperature superconductivity (HTS).

High-Temperature Superconductivity

Japanese Journal of Applied Physics, 2006
A general review on high-temperature superconductivity was made. After prehistoric view and the process of discovery were stated, the special features of high-temperature superconductors were explained from the materials side and the physical properties side.

High-Temperature Superconductivity

Physics Bulletin, 1983
V L Ginzburg and D A Kirzhnits (eds) 1982 New York: Academic xv + 364 pp price $55 One of the authors of this book had previously said 'Yes, high-temperature superconductivity is a dream, but a sufficiently realistic one'. The Bardeen–Cooper–Schrieffer theory of superconductivity is the accepted basis, but the attraction which causes pairing of ...
