The meaningful enhancement in binding energy values and electrical conductivity of h-AlN nanosheet can be potential candidate for detection of formaldehydemolecule.
The adsorption of formaldehyde molecule changed the conductivity of monolayer honeycomb structure especially h-AlN nanosheet.
The favorable adsorption sites of formaldehyde molecule depend on binding energy, HOMO-LUMO gap, Mulliken, Hirshfeld and Voronoi population.
