Fig. 6From: Dilute Magnetic Semiconductor and Half-Metal Behaviors in 3d Transition-Metal Doped Black and Blue Phosphorenes: A First-Principles Study(Color online). Band structures of Ti- and Ni-doped blue phosphorenes obtained using the PBE + U calculation with U = 5.5, 6.5 eV, respectively. The red (black) lines represent the majority (minority) spin band. The energy zero represents the Fermi levelBack to article page
