Fig. 2From: Influence of Thickness on the Electrical Transport Properties of Exfoliated Bi2Te3 Ultrathin FilmsThe measured resistance of the Bi2Te3 ultrathin film with a thickness of 15 nm is plotted as a function of temperature. The left inset shows a typical optical image of the four-terminal electrodes fabricated on a single ultrathin film. The right inset illustrates the details in the area marked by a squareBack to article page
