Description:
Author(s): Wei Li, Hao Ding, Zhi Li, Peng Deng, Kai Chang, Ke He, Shuaihua Ji, Lili Wang, Xucun Ma, Jiang-Ping Hu, Xi Chen, and Qi-Kun Xue We elucidate the existing controversies in the newly discovered K-doped iron selenide (K x Fe 2- y Se 2- z ) superconductors. The stoichiometric KFe 2 Se 2 with √ 2 ×√ 2 charge ordering was identified as the parent compound of K x Fe 2- y Se 2- z superconductor using scanning tunneling microscopy and spectroscopy. The s...
