TL;DR: In this paper, a versatile polysilicon (poly-Si) film intentionally doped with carbon (C) to suppress blistering and improve physical contacts is reported, which shows that the reduced crystallization fraction of poly-Si in conjunction with the suppressed level of hydrogen release should primarily be responsible for the blistering-free appearance of the C-doped polySi films.

Universal energy-level alignment of molecules on metal oxides
Mark T. Greiner,Michael G. Helander,Wing Man Tang,Zhibin Wang,Jacky Qiu,Zheng-Hong Lu,Zheng-Hong Lu +6 more
TL;DR: A universal energy-alignment trend is observed for a set of transition-metal oxides--representing a broad diversity in electronic properties--with several organic semiconductors, demonstrating that, despite the variance in their electronic properties, oxide energy alignment is governed by one driving force: electron-chemical-potential equilibration.
