Bi2Sr2CaCu2O8高温超导体中临界温度的变化规律
Physical Trend for Critical Temperature in Bi2Sr2CaCu2O8 High-temperature Superconductors
摘要
Abstract
Superconductivity is extremely interesting and important in condensed matter physics and material science.Currently,many types of materials exhibit superconductivity with a critical temperature(TC)located in a large range under normal pressure.Compared with the successful Bardeen-Cooper-Schrieffer(BCS)theory for low-TC metals,there are no effective model and theory for high-temperature superconductors.In this work,taking Y-doped Bi2Sr2CaCu2O8 as an example,a power law relationship is obtained for TC and hole concentration.A large hole concentration is beneficial to realize a high TC.This work provides useful guidance for the future discovery of high TC superconductors.关键词
