Organic (TPyP)Eu2[Pc(OPh)8]2/CdS self-assembled hybrid nano-transistors with high ambipolar performance
A new organic/inorganic hybrid bicomponent nanomaterial was obtained by quasi-Langmuir-Shafer (QLS) method with a mixed (phthalocyaninato)-(porphyrinato) europium complex (TPyP)Eu2[Pc(OPh)8]2 and the inorganic material CdS. The conductivity of the (TPyP)Eu2[Pc(OPh)8]2/CdS hybrid film (1.9 × 10−7 S c...
