“…Contrarily to the trend reported in other works, 73,74 a net increase of the bandgap of the investigated heterostructure from 0.13 eV to 0.19 eV is observed upon limonene adsorption. Such a result can be efficiently rationalized by evoking the Moss–Burstein effect, in which limonene behaves as a high n-type doping agent in the p-type degenerate semiconducting heterostructure.…”

“…Even though the limited size of the simulation supercell may in principle affect the bandgap estimate, these values – reported in Table 4 – are significantly larger than those recently found in other similar simulation studies. 73,74 Additionally to the evidence that our computations predict a completely different way of adsorption of the molecule ( i.e. , chemisorption), all these findings indicate a better sensitivity of the proposed heterostructure material toward limonene compared to other reported materials like sensitive g-C 6 N 6 monolayers 73 and germanane.…”

“…Furthermore, it is worth stressing the fact that in spite of the large t at lower temperature regimes, the large E ads would ensure anyway the high capability of sensing very low concentrations of limonene molecules affording very high sensitivity even at low temperatures. Contrarily to the trend reported in other works, 73,74 a net increase of the bandgap of the investigated heterostructure from 0.13 eV to 0.19 eV is observed upon limonene adsorption.
