Abstract Metal oxides are used in a broad array of technological applications. However, only a small subset of oxide materials are semiconducting, which limits the range of chemical compositions available for engineering. Here we demonstrate a strategy for driving insulating metal oxides into a semiconducting state with ultra-low thermal conductivity (less than 1 W/m/K) by introducing configurational entropy.

Phase-Field Model of Electronic Antidoping

|
By Yin Shi, Guo-Dong Zhao, Ismaila Dabo, Shriram Ramanathan
| Physical Review B
Charge carrier doping usually reduces the resistance of a semiconductor or insulator, but was recently found to dramatically enhance the resistance in certain series of materials. This remarkable antidoping effect has been leveraged to realize synaptic memory trees in nanoscale hydrogenated perovskite nickelates, opening a new direction for neuromorphic computing.
