The time response of a photoconductive mat erial (independent of photon energy) can be modeled by the combination of the RC time constant, the transit time of carriers drifting across the crystal, and the relaxation time of carrier trapping and recombination [26] The mobility lifetime product is particularly important for RTSD materials because. The key properties for this capability include insulator-level resistivity values (at least 10 8 Ω cm) that allow for leakage current values lower than several nanoamperes, electron-hole pair creation energies that approach the value of the bandgap, and charge carrier mobilities and lifetimes that enable optimum charge collection efficiency Cited by: 1.

In the case of hole-transporting materials and hole-injecting electrodes (such as Au in the case of ADT-TIPS(TES)-F and TIPS-pentacene), bulk photoconductive gain G ≈ η 0 τ c / t tr E7 (where τ c is the carrier lifetime, and t tr is the time for the hole to transit through the film), and G can be much larger than by: 1.

For the same experiments, we also prepared polycrystalline Pc and TIPS-pentacene thin films. OFETs with BCDPP show unipolar p-type semiconducting properties with hole mobility of × 10−4 cm2 V−1 s−1 and OFETs of BCPzDP exhibit.

This highly conjugated compound is an organic compound generates excitons upon absorption of ultra-violet or visible light; this makes it very sensitive to this reason, this compound, which is a purple powder, slowly degrades upon exposure to air and g point: 40–43 °C (– °F; – K) at torr.

Applying a hot wall deposition method, a hole mobility of only cm 2 /Vs in rubrene has been measured. Obviously sample preparation and purification have a profound effect on the crystal properties, particularly if the sample is polycrystalline instead of single crystalline (Wang et al., Cited by: 1.

The magnitude of the change in the conductivity induced by irradiation can be quantified, from which the electronic properties relating to the charge carrier mobility and lifetime can also be analyzed.

Varying the state of the irradiation between on and off, the photoresponse characteristics of the material can also be achieved. We computed the intermolecular electronic coupling and the band structure of three pentacene derivatives that stack cofacially in one or two dimensions.

We rationalize the results building a map of the coupling between HOMOs and LUMOs of isolated pentacene molecules as a function of the relative molecular orientation and finding the position on such map of the actual Cited by: This paper presents a comprehensive review of the literature on one-dimensional (1D) nanostructures (nanowires, nanoribbons, nanotubes, nanobelts, and nanofibers) of π-conjugated small molecules, oligomers, and polymers.

High photoconductive responsivity approaching 25 AW −1 in a solution‐processed organic composite of rubrene and 9,10‐diphenylanthracene. Studies of photoconductivity, photoluminescence, and structural order ellucidate the role of interfacial traps that lead to a long hole lifetime, which facilitates a high photoconductive gain, resulting.

Graphene and graphene-based materials exhibit exceptional optical and electrical properties with great promise for novel applications in light detection. However, several challenges prevent the full exploitation of these properties in commercial devices. Such challenges include the limited linear dynamic range (LDR) of graphene-based photodetectors, the lack of efficient generation Cited by: 8.

The improvement of oxygen‐barrier properties of glassy polyesters by orientation was examined. Orientation was seen as the process of decreasing the amount of excess‐hole free volume and bringing the nonequilibrium polymer glass closer to the equilibrium (zero‐solubility) condition.
