In this work, we present a novel organic complementary comparator constructed of Pentacene P-channel and Fullerene N-channel thin-film transistors. These organic semiconductor materials are chosen due to their popularity and high effect-field mobility. We fabricated two new organic fieldeffect transistor types, then we measured key parameters in order to create models being used in integrated c...

The development of solution-processable, high-performance n-channel organic semiconductors is crucial to realizing low-cost, all-organic complementary circuits. Single-crystalline organic semiconductor nano/microwires (NWs/MWs) have great potential as active materials in solution-formed high-performance transistors. However, the technology to integrate these elements into functional networks wi...

We study organic microcavities in the strong coupling regime. The cavity exciton-polariton dispersion relations and quantum states are derived in using a microscopic theory. We consider the two cases of anisotropic organic crystals with one and two molecules per unit cell. In general, the cavity exciton-polaritons are a coherent superposition of both cavity mode polarizations and of both Davydo...

We report an effective method for bringing about a significant reduction in the lateral leakage current passing through the non-channel region of an organic semiconductor through an organic solvent vapor treatment. The hydroxyl-containing dimethyl-sulfoxide molecules interrupt the bulk charge transport after undergoing solvent vapor treatment and reduce the lateral leakage current effectively, ...

Ideal photovoltaic cells would be black, absorbing all of the Sun’s radiation, whereas Nature’s machinery for solar energy harvesting— photosynthesis—looks green. Organic semiconductor devices, based on molecular building blocks, lie conceptionally between the extremes of inorganic and photosynthetic light harvesting. How can organic solar cells appear almost black if they are based on molecula...

End-substitution of quarterthiophene and sexithiophene with hexyl groups leads to highly soluble conjugated oligomers, -dihexylquarterthiophene (DH-4T) and -dihexylsexithiophene (DH-6T). We have characterized these oligomers for optical and electrical properties. We fabricated an organic thin film transistor (OTFT) using the above two air-stable p-type organic semiconductor materials. We obtain...

Nowadays new research area focused on hybrid inorganic/organic fibres materials based on bacterial cellulose and inorganic nanoparticles paid attention of many researches. It is well known that homogeneously dispersed nanoscale inorganic particles in a polymer matrix improve the mechanical properties of the resulting nanocomposites. Hybrid materials containing metal or semiconductor nanoparticl...

In this work, lead phthalocyanine (PbPc) and ZnO/InN inorganic semiconductor films prepared by oblique-angle deposition (OAD) were layered to form heterojunction organic/inorganic hybrid photovoltaic solar cells. Among the available organic materials, phthalocyanines, particularly the non-planar ones such as PbPc, are notable for their absorption in the visible and near infrared regions. The or...
