补充资料:BCS穿透深度(BCSpenetrationdepth)
BCS穿透深度(BCSpenetrationdepth)
对纯超导体,由BCS电流方程,在伦敦极限下(`\xi_0\lt\lt\lambda`或$l\lt\lt\xi_0$)的穿透深度与伦敦穿透深度λL(T)相符。对非纯超导体(含杂质),在伦敦极限下为
$\lambda(T)=\lambda_L(T)(1 \xi_0//l)^{1/2}$
一般地,λL(T)由经验公式表示其与温度T的关系(见“伦敦穿透深度”)。在皮帕德极限下($\xi_0\gt\gt\lambda$或$\xi_0\lt\ltl$),ξp=ξ0,则给出为
$\lambda(T)=\frac{8}{9}\lambda_L(T)[\frac{sqrt3\xi_0}{2\pi\lambda_L(T)}]^{1/3}$
