Journal ArticleDOI
Crossover from band-like to thermally activated charge transport in organic transistors due to strain-induced traps
Yaochuan Mei,Peter J. Diemer,Muhammad Rizwan Niazi,Rawad K. Hallani,Karol Jarolimek,Cynthia S. Day,Chad Risko,John E. Anthony,Aram Amassian,Oana D. Jurchescu +9 more
TL;DR: Experimental results suggest that the inhomogeneous strain induced in organic semiconductor layers by the mismatch between the coefficients of thermal expansion (CTE) of the consecutive device layers of field-effect transistors generates trapping states that localize charge carriers.
Journal ArticleDOI
Direct structural mapping of organic field-effect transistors reveals bottlenecks to carrier transport.
Ruipeng Li,Jeremy W. Ward,Detlef-M. Smilgies,Marcia M. Payne,John E. Anthony,Oana D. Jurchescu,Aram Amassian +6 more
TL;DR: Treatment of the bottom Au contacts with pentafl uorobenzene thiol has been shown to dramatically improve carrier transport in bottom-contact OFETs and microstructure and morphology of the organic semiconductor play pivotal roles in mediating device performance.
Journal ArticleDOI
Late stage crystallization and healing during spin-coating enhance carrier transport in small-molecule organic semiconductors
Kang Wei Chou,Hadayat Ullah Khan,Muhammad Rizwan Niazi,Buyi Yan,Ruipeng Li,Marcia M. Payne,John E. Anthony,Detlef Smilgies,Aram Amassian +8 more
TL;DR: In this article, the formation process of the small-molecule organic semiconductor (OSC) 6,13-bis(triisopropylsilylethynyl) (TIPS)-pentacene during spin-coating in the context of an organic thin film transistor (OTFT) application was investigated.
Journal ArticleDOI

Journal ArticleDOI
Growth of vacuum evaporated ultraporous silicon studied with spectroscopic ellipsometry and scanning electron microscopy
TL;DR: In this paper, a combination of variable-angle spectroscopic ellipsometry and scanning electron microscopy was used to investigate the scaling behavior of uniaxially anisotropic, ultraporous silicon manufactured with glancing angle deposition.
