Ultrahigh-stability SnOX (X = S, Se) nanotubes with a built-in electric field as a highly promising platform for sensing NH3, NO and NO2: a theoretical investigation

Combining density functional theory calculations with non-equilibrium Green's-function-based simulations, we systematically investigated the sensing performance of novel ultrahigh-stability SnOX (X = S, Se) nanotubes toward NH 3 , NO, and NO 2 .
