"WebThe conductive paths reduce the resistance to electron flow, making the bulk current more likely than the surface current. In addition, a dielectric barrier (SRO50) was placed between the silicon substrate and the highly conductive SRO10, SRO20 or SRO30, as shown in Figure 1. Therefore, the dark current for these devices is in the bulk SRO. " - Photoelectric barrier
