Ferrimagnetic Slater Insulator Phase of the Surface

JH Lee, HJ Kim, JH Cho - Physical Review Letters, 2013 - APS
We perform semilocal and hybrid density-functional theory (DFT) studies of the Sn/Ge (111)
surface to identify the origin of the observed insulating 3× 3 phase below∼ 30 K. In contrast …
