1.
The results show that the superconducting energy gap (2?(T)) is about 80 meV at Tc (93 K), and decreases smoothly as the temperature increasing.
计算结果表明,其超导能隙值2?(T)在101meV量级;并在超导临界温度点(Tc=93K)附近,有超导能隙不为零的极小值;当温度超过Tc时,YBa2Cu3O7有赝能隙存在,且赝能隙随温度升高至T*=120K时,达到极大值;当温度超过T*时,赝能隙又有明显减小趋势。
2.
The conclusion was that superconducting energy gap could not be obtained by measuring the emergence work of the metal.
指出 :不能通过测量金属的脱出功来测量超导能
补充资料:凝聚能(condensationenergy)
凝聚能(condensationenergy)
对可逆迈斯纳效应所存在破坏超导电性的临界磁场Hc(T),从热力学观点看,其包含的磁能密度也对应着零场下正常态和超导态之间的自由能密度之差,称超导态的凝聚能,即
`f_n(T)-f_s(T)=\frac{1}{2}\mu_0H_c^2(T)`
由上式所表示的Hc(T)又称为热力学临界磁场,它对第一类超导体也就是临界磁场。对第二类超导体,则Hc(T)只表示由上式关系定义的热力学临界磁场,它并不代表相变点,而由第一、第二和第三临界磁场来描绘。
