High-resolution EM of colloidal nanocrystal growth using graphene liquid cells
Jong Min Yuk,Jong Min Yuk,Jong Min Yuk,Jungwon Park,Jungwon Park,Peter Ercius,Kwanpyo Kim,Kwanpyo Kim,Daniel J. Hellebusch,Michael F. Crommie,Michael F. Crommie,Jeong Yong Lee,Alex Zettl,Alex Zettl,A. Paul Alivisatos,A. Paul Alivisatos +15 more
TL;DR: A new type of liquid cell for in situ transmission electron microscopy (TEM) based on entrapment of a liquid film between layers of graphene that facilitates atomic-level resolution imaging while sustaining the most realistic liquid conditions achievable under electron-beam radiation is introduced.

TL;DR: The microscopic origin of the bipolar resistive switching behavior was elucidated and is attributed to rupture and formation of conducting filaments at the top amorphous interface layer formed between the graphene oxide film and the top Al metal electrode, via high-resolution transmission electron microscopy and in situ X-ray photoemission spectroscopy.
Interface-Engineered Amorphous TiO2-Based Resistive Memory Devices
TL;DR: In this paper, the stable bipolar resistive switching in metal/a-TiO2/metal RRAM devices is attributed to both interface domains: the top interface domain with mobile oxygen ions and the bottom interface domain for its protection against an electrical breakdown.
