Abstract:The fullerene-based derivative phenyl-C61-butyric acid methyl ester (PCBM) has attracted attention as an n-type transistor channel and an organic photovoltaic material due to its solution processability, stability, and high electron mobility. However, disorder in solution-processed PCBM thin films makes understanding of charge carrier transport mechanisms difficult. We have fabricated PCBM-based field effect transistors and improved device performance by reducing electron trapping at the dielectric–semiconduct… Show more
“…44 This would bring about a decrease in the Schottky barrier between the metal and the lowest unoccupied molecular orbital (LUMO) of PCBM, in turn associated with an easier electron injection in the PCBM lm, paralleled by higher mobility. 45,46 The surface of electrodes from commercial Pd is more hydrophobic (contact angle of 90.4 ± 3.5°, Fig. S6 †) than that of the recycled Pd counterparts (85.6 ± 2.6°).…”
Palladium is a non-toxic platinum group metal indispensable for several industrial applications. It is among the 44 endangered elements; hence, its recycling from secondary sources is crucial. Fashion solid residues...

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
