2020年10月1日 · In this study, we provide a new investigation on the effect of tuning the ratio of OXCBA, their optical, morphological and electrical properties, thus determining the compatibility of OXCBA with P3HT in the application of a photodetector by evaluating their …

2020年6月5日 · In the C1s spectrum of P3HT, the peak at 284 eV is associated with C C bond binding state of C element (Schwarz et al., 2017b), and the peak located near 286 eV is associated with C S bond binding state of C element (Silva Santos et al., 2019), these peaks are contributed by the thiophene ring chemical structure (Sportelli et al., 2017).

2010年11月1日 · PCBM exhibits C1s – to – π* transitions at 284.5 eV and 285.8 eV whereas the C1s – to – π* transition of P3HT occurs at 285.13 eV [22]. Carefully monitoring the NEXAFS spectra in this region thus provides a unique fingerprint for the species in question.

P3HT C 1s XPS peak •Lowest EUV dose dramatically alters P3HT C1s peak to similar shape and energy of typical admitted-gas EUV-C. •C1s binding energy shifts toward graphitic state with increasing EUV dose – as observed with admitted-gas EUV-C deposits. •Similar trend in PVDF and all admitted-gas exposures 12 EUV exposures of P3HT

As model system, we use poly(3-hexylthiophene-2,5-diyl) (P3HT) and blends of P3HT with PCBM. P3HT is an ideal p-type semiconductor and a widely used conjugated polymer. We investigate the regioregular-P3HT (rr-P3HT) phase with high carrier mobility (up to 0.1 cm 2 V −1 s −1) in relation to regiorandom-P3HT (10 −5 cm 2 V −1 s −1) [17, 18].

Figure 5a shows the C1s core-level spectrum, which presents peaks related to the C-C/C = C bonds of thiophene and fullerene, peaks associated with carbon linked to oxygen atoms due to the...

2020年5月5日 · Proposed a new way of synthesizing Z-scheme systems and immobilizing Z-scheme photocatalysts. Charge transfer mechanism in P3HT/α-Fe 2 O 3 nano-array is discussed in detail. Z-scheme P3HT/α-Fe 2 O 3 nano-array exhibits excellent photodegradation performance. Possible degradation pathways are proposed.

In this study, we investigate the effect of the solvent and of the substrate modification on thin films of organic semiconductor Poly (3-hexylthiophene) (P3HT) in order to improve the stability and electrical properties of an Electrolyte Gated Organic Field Effect Transistor (EGOFET) biosensor.
