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.

Webequations. Einstein and Millikan described the photoelectric effect using a formula (in contemporary notation) that relates the maximum kinetic energy ( Kmax) of the photoelectrons to the frequency of the absorbed photons ( f) and the threshold frequency ( f0) of the photoemissive surface. Kmax = h ( f − f0) WebSafety Light Curtains – Photoelectric Sensors – Light Barriers – Perimeter Access Control.
