Undoped graphene helps in detection of supercollision cooling !

The flexibility of changing the Fermi energy level of graphene by a voltage has proven to be a blessing in many applications. Especially  optoelectronics and photonic application of graphene have emerged. 
A new finding reveals the detection of supercollision, i.e. collision of charge carriers with both phonons and impurities, in graphene. The study proves to be useful for bolometric and photo-detection applications of graphene.
