Under this circumstance, electrons will absorb the photons and jump to the excited state, i.e. the film is opaque. By applying a negative voltage V < 0 to the substrate, however, the BFO film transforms to G-type AFM. Since now the energy gap is larger than the photon energy...
Again, this circumstance also changes when considering Conditional Entropies (H(X/C) or H(X/nC)). For Specific Information, the achieved values differ once more in comparison with other metrics values. However, it can be noted that the value reached for the change category in the Kb_...
