Abstract
Layered structures such as photosensing arrays include layers in which charge carriers can be transported. For example, a carrier-transporting substructure that includes a solution processing artifact can transport charge carriers that flow to or from it through charge-flow surface parts that are on electrically conductive regions of a circuitry substructure; the circuitry substructure can also have channel surface parts that are on semiconductive channel regions, with a set of the channel regions operating as acceptable switches in an application. Or a first substructure's surface can have carrier-active surface parts on electrode regions and line surface parts on line regions; a second substructure can include a transport layer on carrier-active surface parts and, over it, an electrically conductive layer; to prevent leakage, an open region can be defined in the electrically conductive layer over the line surface part and/or an electrically insulating layer portion can cover the line surface part.
