Abstract
THE APPLICATION OF ORGANIC SEMICONDUCTOR MATERIALS AS THIN FILM LIGHT EMITTERS IS STUDIED. THE MATERIALS EXAMINED ARE THE METAL PHTHALOCYANINES AND CHEMICALLY DOPED VARIATIONS. THEY ARE DEPOSITED ON CONTROLLED SUBSTRATES BY AN ULTRAHIGH VACUUM MOLECULAR BEAM EXPITAXY APPROACH TO ENHANCE FILM CRYSTAL GROWTH IN A PLANARSTACKED RING MOLECULAR ORIENTATION THAT IS EXPECTED TO GIVE PROPERTIES DIFFERENT FROM THE NORMAL BULK CRYSTALLINE MATERIAL. THIS FORM OF FILM GROWTH WILL PROVIDE A MEANS OF MODULATING ELECTRONIC STRUCTURE WITHIN THE FILM TO PRODUCE ORGANIC HETEROJUNCTION STRUCTURES BY DOPING THE FILM SELECTIVELY LAYER BY LAYER TO PRODUCE DEVICE STRUCTURES IN THIS THIN FILM ORGANIC SEMICONDUCTOR MATERIAL. THE ELECTRONIC STRUCTURE OF COMPOSITIONALLY AND ELECTRICALLY MODULATED THIN FILM STRUCTURES OF THESE MATERIALS IS STUDIEDFOR ITS IMPLICATIONS ON LIGHT EMISSION FROM THESE MATERIALS.EXCITATION OF RADIATIVE CARRIER RECOMBINATION UNDER CHARGE CARRIER INJECTION IN THESE MATERIALS IS EXAMINED. THESE PROPERTIES ARE BEING STUDIED FOR POTENTIAL APPLICATION IN LIGHT EMITTING DIODE AND LASER DIODE APPLICATIONS.
