Figure 2: TER in submicron Au/PVDF/W tunnel junctions.
From: Tunnel electroresistance through organic ferroelectrics

(a) Three-dimensional sketch of the design of PVDF ferroelectric tunnel junctions. (b) I–V curves in the 1 and 2Ls PVDF FTJs. The arrows show the direction of the voltage sweeps. The two different data colours are obtained on two different junctions for each sample.
