Furan substituted diketopyrrolopyrrole (DBF) combined with benzothiadiazole based polymer semiconductor PDPP-FBF has been synthesized and evaluated as an ambipolar semiconductor in organic thin-film transistors. Hole and electron mobilities as high as 0.20 cm(2) V(-1) s(-1) and 0.56 cm(2) V(-1) s(-1), respectively, are achieved for PDPP-FBF.
Particle aggregation and film agglomeration have been among the main technical hurdles for solid-state thin film development and have been observed in many semiconductor and catalytic systems. In heterogeneous catalysis, particle aggregation leads to reduction of effective surface area and degradation of catalytic performance. On semiconductor surfaces, film agglomeration may give rise to elect...
We study the roughening process and morphology transition of organic semiconductor thin film induced by molecular orientation in the model of molecular semiconductor copper hexadecafluorophthalocyanine (F16CuPc) using both experiment and simulation. The growth behaviour of F16CuPc thin film with the thickness, D, on SiO2 substrate takes on two processes divided by a critical thickness: (1) D ≤ ...
Resistance switching random access memory (RRAM) has drawn considerable attention for the application in nonvolatile memory element in semiconductor memory devices. A ZnO thin film now assumed to be useful for dynamic random access memory (DRAM) cell. In this paper we provide a framework to its use as a switching ON or OFF in DRAM cell. In this type of memory cell the ZnO thin film has a lot of...

A thin-film transistor: An n-type polymer semiconductor, poly(2,3-bis(perfluorohexyl)thieno[3,4-b]pyrazine), was synthesized through a Pd-catalyzed polycondensation employing a perfluorinated multiphase solvent system. This is the first example of an n-type polymer semiconductor with exclusive solubility in fluorinated solvents. The fabrication of organic field effect transistors containing thi...
Semiconductor-based solid-state neutron detectors have received considerable attention in recent years. These devices can be categorized as either thin-film-coated diode detectors or solid-form bulk detectors. There have been many attempts to fabricate boron-based solid-form detectors utilizing processing techniques similar to those frequently used to fabricate thin-film-coated diodes. Conseque...
We demonstrate a novel display structure for color electronic paper for the first time. Fully transparent amorphous oxide TFT array is directly deposited onto color filter array and combined with E Ink Imaging Film. Taking advantage of the transparent property of the oxide TFT, the color filter and TFT array are positioned at the viewing side of the display. This novel “Front Drive” display str...
We report the implementation of three dimensionally cross-linked, organic nanodielectric multilayers as ultrathin gate dielectrics for a type of thin film transistor device that uses networks of single-walled carbon nanotubes as effective semiconductor thin films. Unipolar n- and p-channel devices are demonstrated by use of polymer coatings to control the behavior of the networks. Monolithicall...
