“…4 summarizes the comparison between predicted hole mobility values from this work and experimental measurements reported in the literature. The low-to zero-field experimental mobility values for these compounds were taken from independent reports by Wu and coworkers (mCP) [28], Kwak and coworkers (NPB) [29], Tsai and coworkers (CzC) [30], Chan and coworkers (2TNATA, TCTA, TPD, and spiro-TPD) [31], and Okumoto and coworkers (o-BPD, m-BPD, and p-BPD) [32], respectively. The experimental mobilities shown in this work for comparison are all from time-of-flight (TOF) measurements.…”

Transition-metal oxides (TMOs), such as WO 3 , MoO 3 , V 2 O 5 , and ReO 3 , have been widely used as p-type dopants for organic semiconductors to improve device performances. However, it still remains unclear how charges transport after doping TMOs into organic materials. Here, Monte Carlo simulations are used to study the mechanisms of charge transport in TMO-doped organic semiconductors in a hole-only device. It is found that the charge carriers and the electric field are redistributed after the doping of TMOs, and the density of states distribution broadens. Furthermore, it is shown that new charge transport pathways are formed at medium-to-high doping ratios, leading to more efficient charge transport. At low energetic disorders, the charge mobility drops with the doping of TMOs. However, when the energetic disorder is high, the charge mobility will be improved at high doping ratios of TMOs. The conclusions will also help the understanding of the charge-transport process in electrochemical doped systems.

“…Hole mobilities (μ h ) of up to 5.3 × 10 −6 cm 2 V −1 s −1 were calculated at the saturation regime (V D << V G ) from the transfer characteristics and averaged for the different sets of transistors. Hence, the mobilities are satisfying for a nonconjugated amorphous polymer, considering reported values in the range of 10 −7 –10 −5 for typical amorphous organic semiconductors . The on/off ratios of the devices are in the range of 10 4 with an onset voltage of approximately −20 V.…”

Front Cover: The properties of elastomers are exploited to trigger wrinkling instabilities in curved shells. Each electro-spun micro-or nanofi ber consists of a soft core and a stiff outer half-shell, which are length-mismatched because of differential solvent de-swelling. The fi bers only wrinkle after attaining a well-defi ned helical shape. A simple analytical model is proposed to fi nd the curvature and wrinkle wavelength. Further details can be found in the article by Stimulus-sensing biohybrid materials have attracted signifi cant interest as smart materials with applications especially in the biomedical fi eld. Such materials harnessing unique properties of chemical and biological polymers are engineered to translate molecular stimuli into precisely defi ned mechanical material properties. This article gives an overview of how biological polymers can be used to control material properties and on their applications.
