最后是我自己设置的参数文献中所给计算参数为截断能550eV，能量收敛为10的-7次方，k点网络为5x5x5,采用晶体结构为在1x2x1的KNbO3超胞中替换1个K原子得到的K0.5Na0.5NbO3结构，请问有大佬...

用CASTEP进行结构优化，优化KNbO3时可以正常进行优化，优化时间也短；优化K0.5Na0.5NbO3时就出现thejobisfailed，但是这俩的cif文件都是从Findit下载的，结构一样，原子数也一样，为什么会...

想请教一下，最近用过量的碳酸钾（另一个是氧化铌）进行顶部籽晶法生长KNbO3,用的是白金丝吊晶体，但是一点晶体都吊不上来，大概960度就凝固了，这是正常的吗？还是必须用KNbO3的籽晶呢，...

各位同行，麻烦问一下，KNbO3是半导体，溶于水吗？若是溶于水还有半导体性质吗？钾离子在其中起到什么作用，换成其他金属可以吗？谢谢各位！zyhoulxg133298kinkilyou
