Fig. 7From: Effects of Asymmetric Local Joule Heating on Silicon Nanowire-Based Devices Formed by Dielectrophoresis Alignment Across Pt ElectrodesSchematic energy band diagrams for n-type Si/Pt contacts after DC-DEP alignment (top center). The device went through the asymmetric Joule heating process as the voltage was applied to the drain electrode by sweeping from positive to negative bias in method 1 (left) or negative to positive bias in method 2 (right)Back to article page
