Imaging Fermi-level hysteresis in nanoscale bubbles of few-layer MoS2

open access: yesCommunications Materials, 2023
The electrical stability and reliability of two-dimensional (2D) crystal-based devices are mainly determined by charge traps in the device defects. Although nanobubble structures as defect sources in 2D materials strongly affect the device performance ...

Structural behaviour of copper chloride catalysts during the chlorination of CO to phosgene [PDF]

open access: yes, 2018
The interaction of CO with an attapulgite-supported Cu(II)Cl2 catalyst has been examined in a micro-reactor arrangement. CO exposure to the dried, as-received catalyst at elevated temperatures leads to the formation of CO2 as the only identifiable ...
