Fig. 8From: Band Gap Characters and Ferromagnetic/Antiferromagnetic Coupling in Group-IV Monolayers Tuned by Chemical Species and Hydrogen Adsorption ConfigurationsThe difference of total energies between AFM and FM states for semihydrogenated monolayer SiC with chair SiC-H configuration (yellow line) and semihydrogenated monolayer GeC with chair GeC-H configuration (green line). The AFM-FM transition occurs at an interatomic distance of 3.180 Å (3.223 Å) for SiC-H (GeC-H)Back to article page
