Nevertheless, the presence of an electric field is not the only way to obtain contact selectivity. It can also be attained by a preferential kinetic exchange at one selective contact of carriers of one kind while the other kind is blocked. Figure 1 C is an example of this, where light is absorbed by a dye molecule layer and electrons are selectively …
