TL;DR: In this paper, the authors report artifact-free CH3NH3PbI3 optical constants extracted from ultra-smooth perovskite layers without air exposure and assign all the optical transitions in the visible/ultraviolet region unambiguously based on density functional theory (DFT) analysis that assumes a simple pseudo-cubic crystal structure.
Journal ArticleDOI

Solution-processed n-type organic thin-film transistors with high field-effect mobility
Masayuki Chikamatsu,Shuichi Nagamatsu,Yuji Yoshida,Kazuhiro Saito,Kiyoshi Yase,Koichi Kikuchi +5 more
TL;DR: In this article, a solution-processed n-type organic thin-film transistors (OTFTs) based on C60 derivatives were used as a semiconducting layer, and the C60MC12-thin-film transistor showed high electron mobility of 0.067cm2∕Vs in saturation regime.
