The Cl functionalized aluminum nitride (AlN) and aluminum phosphide (AlP) nanocone sheetsas hydrogen selenide (H2Se) sensor: A density functional investigation

Abstract

The adsorption of H2Se molecule on AlN-NCS and AlP-NCS surfaces were investigated by using of DFT calculations. The potentials of Cl-functionalized AlN-NCS and AlP-NCS for H2Se adsorption were examined. All processes of H2Se-adsorption on considered nanocone sheets were exothermic reactions. The calculated |Ead| amount of complex H2Se with AlP-NCS was higher than AlN-NCS. The functionalization of considered nanocone sheets with Cl atom increase |Ead| amount of H2Se. Results reveal that, obtained Ead amounts of considered nanocone sheets have linear relationships with corresponding orbital energy amounts. Finally, the novel nanocone sheets with higher efficiency to adsorption of H2Se can be proposed.
