Experimental evidence is presented that demonstrates how a light pulse incident upon a ID semiconductor, PDATS, in zero field, seeds that semiconductor with charge held in a stable state, unrecombined, for times on the order of milliseconds. Application of an electric field at later time releases some of this seed charge which is measured whilst the remainder recombines. Two models for this effect are put forward and discussed and an idea for a molecular logic unit, the transactor, is introduced.
