Alternatively, doping of MoTe 2 also shows promise in enhancing the sensing performance of the sheet. Sensor activity critically depends on the transfer of either holes or electrons from the analyte to the sheet, thereby modifying properties such as conductivity and photoluminescence. However, when evaluating the sensor functionality for selected species, a concern arises regarding whether there is a specific adsorption configuration that leads to a large adsorption energy. Such a strong interaction could impede the rapid recovery of the sensor after evacuating the analyte, hindering the response to fast changes in concentration. Hence, to tune the sheet's properties toward sensing, doping should enhance charge transfers with a limited impact on the adsorption energy. Consequently, the results suggest that the best dopants for acceptor-type molecules are Pb, Bi, and group 17 elements due to their relatively high charge transfer compared to their adsorption energies.
