Freestanding LiPON: from Fundamental Study to Uniformly Dense Li Metal Deposition Under Zero External Pressure
Diyi Cheng, Thomas Wynn, Bingyu Lu +12
Lithium phosphorus oxynitride (LiPON) is a well-known amorphous thin film solid electrolyte that has been extensively studied in the last three decades. Despite the promises to pai…
Unraveling the stable cathode electrolyte interface in all solid-state thin-film battery operating at 5V
Ryosuke Shimizu, Diyi Cheng, Minghao Zhang +6
Spinel-type LiNi0.5Mn1.5O4 (LNMO) is one of the most promising 5 V-class cathode materials for Li-ion batteries that can achieve high energy density and low production costs. Howev…
Imaging real-time amorphization of hybrid perovskite solar cells under electrical biasing
Min-cheol Kim, Namyoung Ahn, Diyi Cheng +11
Perovskite solar cells have drawn much attention in recent years, owing to its world-record setting photovoltaic performances. Despite its promising use in tandem applications and…
2D van der Waals Nanoplatelets with Robust Ferromagnetism
Michael C. De Siena, Sidney E. Creutz, Annie Regan +9
We have synthesized unique colloidal nanoplatelets of the ferromagnetic two-dimensional (2D) van der Waals material CrI3 and have characterized these nanoplatelets structurally, ma…
