在含Bi方网的Y_2O_2Bi中，H取代和Li嵌入导致较高的超导转变温度（Tc），而F取代导致较低的Tc，其中Tc普遍用晶胞四方性c/a标度。Li插层的Y2 O2 Bi显示出比以前报道的Y2 O2 Bi更高的Tc，即使对于类似的c/a。
In Y2O2Bi with Bi square net, H substitution and Li intercalation led to higher superconducting transition temperature (Tc), while F substitution led to lower Tc, where Tc is universally scaled by unit cell tetragonality c/a. Li intercalated Y2O2Bi showed a higher Tc than previously reported Y2O2Bi even for the similar c/a.
