Figure 1From: First-Principles Study of Magnetic Properties of 3d Transition Metals Doped in ZnO Nanowiresa The ZnO nanowire unit-cell andb bulk unit-cell are studied here. Thegrey spheres are Zn,yellow are O,red are H1.5, andblue are H0.5. Thegreen spheres are the Zn sites substituted with Cr atoms or other TM atoms. The geometry is before relaxationBack to article page
