Thickness Scaling Effect on Interfacial Barrier and Electrical Contact to Two-Dimensional MoS<sub>2</sub> Layers
Thickness Scaling Effect on Interfacial Barrier and Electrical Contact to Two-Dimensional MoS<sub>2</sub> Layers
Understanding the interfacial electrical properties between metallic electrodes and low dimensional semiconductors is essential for both fundamental science and practical applications. Here we report the observation of thickness reduction induced crossover of electrical contact at Au/MoS2 interfaces. For MoS2 thicker than 5 layers, the contact resistivity slightly decreases with reducing …
