- 論文の詳細を見る
We report variable range hopping conduction (VRHC) in the insulating phase nearthe metal-insulator transition in Al...Ga(,..As:Si. In the VRHC region, the tempera-ture dependence of the resistivity obeys Efros and Shklovskii's T"' law rather thanMolt's T"' law. This means the Coulomb repulsion effect is important to thetransport in this system. These results and those of dielectric constant measurementsreported previously are explained by Efros and Shklovskii's theory. On the otherhand, the magnetoresistance in VRHC is negative; no clear theoretical explanationhas been found for this.
