Abstract: Electrical sensitivity of a Rollators beryllium oxide nanotube (BeONT) was examined toward (C5H5N) molecule by using density functional theory (DFT) calculations at the B3LYP/6-31(d) level, and it was found that the adsorption energy (Ead) of pyridine on the pristine nanotubes is a bout -73.29kcal/mol.But when nanotubes has been doped with S and P atomes , the adsorption energy changed.Calculation GLAZIERS STICK showed that when the nanotube is doping by P, the adsorption energy is about -39.
59kcal/mol and also the amount of HOMO/LUMO energy gap (Eg) will reduce significantly (Eg=2.55Ev).The BeONT doped with P is suitable semiconductor than the pristine BeONT.
