Which of the following factors is not responsible for the maintenance of Quantum Hall Effect (QHE) in graphene at high temperatures? Correct Answer Electrical resistivity

Quantum Hall Effect in graphene survives at high temperatures due to different factors. These are mainly the large cyclotron gap, high carrier concentrations (up to 1013cm2) with only a 2D sub band filled and the unchanged mobility of dirac fermions.
