Mott phase
Nettet10. sep. 2024 · DFT + DMFT results reveal the existence of a site-selective Mott phase at V = 0.71 V 0 (b), in which the 3 d electrons of only half of the Fe sites (right: B sites) are metallic, while the other Fe (left: A sites) remain insulating. For V = 0.97 V 0 (6 GPa), we obtain a conventional Mott insulating phase in which both the Fe A and B sublattices ...
