Applications, molecular electronics rectifier

Finally, aside from the OLEDs and solar cells described in Chap. 11, a series of other devices for macroscopic molecular electronics have been demonstrated, in which numbers of organic molecules carry out a specific function. We mention rectifiers, transistors, and storage elements. These will be discussed in Sects. 12.5, 12.6, and 12.7. Instead of a crystal, most of the conceivable applications in molecular electronics will presumably make use of organised and structured films. The preparation and characterisation of such films is therefore particularly important [21, 22]. We shall, however, not treat it in detail here. 

The progressive expansion of the set of relevant channels eis R increases also complements, indeed rectifies, the current treatments of multicheinnel atomic jind molecular processes [9]. These treatments center on the excitation of one (or a very few) electrons, or other degrees of freedom, out of a ground state core. Wavefunctions representing such alternative excitations in different channels are represented semianalytically in the space surrounding the core radius tq, but are interrelated through their respective boundary conditions at tq. The number of relevant channels is chosen judiciously for each application it would increase substantially upon the inclusion of inner-shell excitations. The present hyperspherical approach replaces this ad-hoc...
