Sensors made with atomically thin layers of MoS2 revealed better selectivity to certain gases owing to the electron energy band gap in this material, which resulted in strong
suppression of electrical current upon exposure to some of the gases.
As a result, the engineered quantum dots feature nearly complete
suppression of Auger effect's heat loss, and this allows for redirecting the energy released by the
electrical current into the light - emission channel instead
of wasteful heat.
