Amorphous Gallium‐Oxide‐Based Non‐Filamentary Memristive Device with Highly Repeatable Multiple Resistance States

Advanced Electronic Materials
A memristive device is presented based on a Ti/GaOx/W stack with an amorphous GaOx layer deposited at a low temperature (250 °C) using plasma‐enhanced atomic layer deposition. The device fabrication is compatible with a standard complementary metal oxide

Quantum size effects on magnetism in Eu2MnHfO6 nanoparticles: Role of surface-to-volume ratio, magnetic blocking, and magnetic phase transitions

Results in Physics
In this paper, we investigate the quantum size effects on Eu2MnHfO6 (EMHO) nanoparticles (NPs) synthesized via sol–gel and annealed at 500, 800, and 1000 °C.

Machine learning approaches to identify and design low thermal conductivity oxides for thermoelectric applications

Data-Centric Engineering, 2020
The search space for new thermoelectric oxides has been limited to the alloys of a few known systems, such as ZnO, SrTiO3, and CaMnO3. Notwithstanding the high power factor, their high thermal conductivity is a roadblock in achieving higher efficiency ...

Study on the piezoresistivity of Cr-doped V2O3 thin film for MEMS sensor applications

Microsystems & Nanoengineering
Cr-doped V2O3 thin film shows a huge resistivity change with controlled epitaxial strain at room temperature as a result of a gradual Mott metal-insulator phase transition with strain.
