在生长过程中通过改变气氛制备了c -取代YBa2Cu3O7 -δ (C-YBCO)单晶。随着大气中CO2浓度的增加，晶体中的碳含量增加，c轴长度减小。从不同退火条件下的Tc变化和磁化率结果可以发现，C-YBCO没有进入载流子过掺杂区，而未取代的样品可以进入载流子过掺杂区。这表明碳取代干扰了氧的扩散，从而抑制了载流子掺杂。（©2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim）
Single crystals of C-substituted YBa2Cu3O7–δ (C-YBCO) were prepared by changing atmosphere in a growing process. With increasing the CO2 concentration in the atmosphere, the carbon content in a crystal increases, and the c -axis length decreases. From the Tc change under various annealing conditions and the magnetic susceptibility results, it was found that C-YBCO does not enter the carrier-overdoped region, while the non-substituted samples can. It suggests that the carbon substitution disturbs the oxygen diffusion, resulting in a suppression of carrier doping. (© 2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
