ORGANIC SEMICONDUCTOR SUPERLATTICES AS AN ATTRACTIVE PERSPECTIVE

Organic/amorphous semiconductor superlattices are built up by means of alternating application of two different methods for thin film format ion. Organic sublayers of cadmium arachidate are deposited by means of the Langmuir-Blodgett technique, and inorganic sublayers of amorphous CdSe are grown via the thermal vacuum evaporation method. The details of the superlattice preparation providing deposition of smooth and ho mogeneous sublayers are described. The periodicity of the structures o btained is evidenced by means of the small-angle X-ray diffraction met hod. The experimental realization of this new type artificial periodic structures opens a number of possibilities for the combination of the advantages of superthin ordered organic and the semiconductor films. The areas of application of such superlattices are outlined.
