To elucidate in more detail the localization of the states in gap region, we obtained the electronic charge density to BNNT plusFeCl3 (CrO3) molecule in more stable configuration. Analyzing the charge density distribution, it is possible to infer that the gap states are localized the molecules. So, Fig. 4(a) shows the charge density distribution, in energy range −5.45 eV to −4.50 eV (see Fig. 2(b)), of FeCl3molecule adsorbed in the BNNT, while Fig. 4(b) shows the charge density, in region −3.95 eV and −3.33 eV (see Fig. 3(b)), toFeCl3 molecule interacting BNNT. In both systems the contribution is exclusively from the states minority spins of the molecules. By these electronic charge density plots, we observe the hybridization of the molecule levels with the nitrogen levels from the BNNT. The FeCl3 and CrO3 molecules interact through a chemisorptions regime on the BN nanotube.
