WitrynaThey show that strong localization e ects are to be expected for energies very close to the Dirac point. In the case of positive bias, when the gate induced gap is lled by impurity states, these states in the gap are strongly localized. Our results suggest that, independently of the bias and for large impurity concentration, localization e ects WitrynaImpurity records in polar ice cores have provided invaluable insights into atmospheric aerosol concentrations of the past environment.
