WebJun 28, 2015 · Random grain boundaries (indicated by b and c in Figure 4.23) give the impression that the film consists of small crystallites of irregular shape. Within these so-called crystallites, E 3-type GBs can be found. The E3-type GBs are indicated by a, d … WebJun 4, 1998 · Carrier transport at grain boundaries is described as it has been developed from the studies on germanium and III‐V‐compound bicrystals. Important features are lateral blocking layers, longitudinal or sheet conduction, space‐charge extension with lateral bias, recombination and photovoltaic effects.
