“…PEDOT:PSS represents the next-generation of electrodes because of its high transparency in the visible range, its solution processability, its high work function, and its significant mechanical flexibility. [1][2][3][4][5][6][7][8][9][10][11][12][13][14] With the widespread use of PEDOT:PSS, a number of studies are attempting to determine and improve its properties. A common method that is used to improve the properties of PEDOT:PSS is a chemical treatment that involves the addition of co-solvents, which results in considerable improvement to the polymer's conductivity.…”

The effect of incorporation of ethylene glycol (EG) into poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) on electron phonon coupling and conductivity is investigated. It is shown that the carrier density (NC) increases significantly and the carrier mobility (μ) increases slightly at 300 K. The increased intensity of the Raman spectrum between 1400 and 1450 cm−1, following EG treatment (that is, the quinoid-dominated structures of the PEDOT chain), leads to an increase in the number of polarons (bipolarons), which leads to an increase in NC. In addition, μ in PEDOT:PSS samples with or without EG addition exhibits a strong temperature dependence, which demonstrates the dominance of tunneling (hopping) at low (high) temperatures. The high conductivity of PEDOT:PSS samples with the addition of EG is attributed to the combined effect of the modification of the electron-phonon coupling and the increase in NC (μ).

“…Moreover, one can achieve tunable optoelectronic properties of GO by modifying its oxygenated functional groups either chemically or thermally [20,23]. Numerous studies have been reported prospecting their applications in photo detectors [24], thin film transistors [25], transparent conducting electrodes [26] and supercapacitors [27]. Recently, several research groups reported remarkable nonlinear optical properties of graphene and GO, such as nonlinear absorption and broadband optical limiting, two-photon absorption (TPA) [28,29], saturable absorption [30] and excited state absorption (ESA) [31], which make GO an ideal material for photonic and optoelectronic applications.…”

Mono- to few-layered graphene oxide embedded randomness assisted microcavity amplified spontaneous emission source

et al. 2015

The realization of optoelectronic devices using two-dimensional materials such as graphene and its intermediate product graphene oxide (GO) is extremely challenging owing to the zero band gap of the former. Here, a novel amplified spontaneous emission (ASE) system based on a GO-embedded all-dielectric one-dimensional photonic crystal (1DPhC) micro-resonator is presented. The mono- to few-layered GO sheet is inserted within a microcavity formed by two 5-bilayered SiO2/SnO2 Bragg reflectors. Significantly enhanced photoluminescence (PL) emission of GO embedded in 1DPhC is explicated by studying the electric field confined within the micro-resonator using the transfer matrix method. The inherent randomness, due to fabrication limitations, in the on-average periodic 1DPhC is exploited to further enhance the PL of the optically active micro-resonator. The 1DPhC and randomness assisted field confinement reduces the ASE threshold of the mono- to few-layered weak emitter making the realization of an ASE source feasible. Consequently, ASE at the microcavity resonance and at the low-frequency band-edge of photonic stop-band is demonstrated. Variation of the detection angle from 5° to 30°, with respect to the sample surface normal allows reallocation of the defect mode ASE peak over a spectral range of 558-542 nm, making the GO-incorporated 1DPhC a novel and attractive system for integrated optic applications.

In addition, the effect of charge trapping on the electrical properties of the organicon-inorganic diode has yet to be elucidated in detail.…”

In this study, the effect of the incorporation of ZnO nanoparticles into [6,6]-phenyl C61-butyric acid methyl ester (PCBM) on carrier transport of PCBM/p-type Si diodes was examined. Correlation effects were evaluated using the well-known expressions for the thermionic emission and space charge limited current. Rectification behavior is affected by the bulk effects of the PCBM layer. It is shown that the incorporation of ZnO nanoparticles leads to the suppression of trap filling effects of the PCBM layer, resulting in improvement in the electrical and optoelectronic performances for PCBM/p-type Si diodes.
