Nanocontacts give efficient hole injection in organic electronics

Organic Light-Emitting Diodes with F16CuPC as an Efficient Hole-Injection Layer

We report a new hole-injection material, copper hexadecafluorophthalocyanine (F16CuPC) for organic light-emitting diodes (OLEDs) consisting of N,N’-di(1-naphthyl)-N,N’-diphenylbenzidine (α-NPD) as a hole-transport layer and 8-tris-hydroxyquinoline aluminum (Alq3) as a light-emitting and electron-transport layer. The insertion of the F16CuPC between indium-tin oxide (ITO) and α-NPD reduces the o...

Carrier injection at silicide/silicon interfaces in nanowire based-nanocontacts

Chapter 28. Organic Optics and Electronics Organic Optics and Electronics

Alternating current thin-film electroluminescent (AC-TFEL) devices already occupy a segment of the large-area, high-resolution, flat-panel-display market. The AC-TFEL displays, which consist of a phosphor layer, such as manganese doped-zinc sulfide (ZnS:Mn), vertically sandwiched between two insulators that are contacted by electrodes, are robust, possess long lifetimes, and offer high luminanc...

Solution-processable dendric triphenylamine nonamers as hole-transporting and hole-injection materials for organic light-emitt

We demonstrated two solution-processable triphenylamine dendric nonamers: the N-atom-centered nonamer (TPA9-1) and the phenyl-centered nonamer (TPA9-2). The materials were found to have high glass transition temperature (Tg) up to almost 200°C. The fractional difference of the central units of the molecular structures caused different adaptability due to the different ionization potentials (Ip)...

Hole mobility enhancement by chain alignment in nanoimprinted poly„3-hexylthiophene... nanogratings for organic electronics

The authors report that the poly 3-hexylthiophene-2,5-diyl P3HT nanogratings shaped by nanoimprint lithography show enhanced hole mobility and strong anisotropy of conductance due to nanoimprint-induced three-dimensional polymer chain alignment. Field effect transistors were fabricated using these nanogratings and device measurements show a hole mobility of 0.03 cm2 /V s along the grating direc...
