The density functional theory calculations are applied for C20 cage fullerenes. Furan, pyrole, and phenylvinyle monomers are made to interact with a C20 cage at the same C position. An electric field was applied with varying strength. Computations were carried out for all cases at the B3LYP/6-31G* level. The structure, energetic, and relative stabilities of the compounds were compared with each other and analyzed. In addition, the electric field dependent and independent electronic transition spectra of the proposed stable neutral C20 cage are investigated.

No Absorption

Functionalization of [Formula: see text] monolayer doped by the transition-metal Fe adatom [Formula: see text]–[Formula: see text] and NO absorption on [Formula: see text]–[Formula: see text] has been investigated computationally using first-principles calculations based on the density functional theory. We found that the system of [Formula: see text]–[Formula: see text] remains a semiconductor, with spin polarization at the Fermi level. However, for the system with absorption of NO molecule on the surface of [Formula: see text]–[Formula: see text] monolayer, its spin polarization is turned over at the Femi level, which provides a promising material for spintronic sensors.
