Resistance Drift of Phase Change Materials Beyond the Power Law

Advanced Electronic Materials, EarlyView.
The timedependent resistance of phase change materials is important for their application as electronic memory. Here, resistance measurements of melt‐quenched germanium telluride from nanoseconds to minutes are presented. By going far beyond the usually considered measurement regime, deviations from the ubiquitous power law behavior are observed, that ...

Multi‐Walled Carbon Nanotubes Suspensions as Liquid Conductors: Electrical and Mechanical Network Interplay

Advanced Electronic Materials, EarlyView.
The interplay between the mechanical and electrical network of multi‐walled carbon nanotubes suspended in glycerol is studied. The study distinguishes three regimes depending on the mechanoelectrical properties of these electrofluids. Electrofluids transition between regimes upon mechanical deformation, leading to electrically conductive suspensions ...

Enhancing Thermoelectric Performance of Cd₃P₂ by Alloying with Dirac Material Cd₃As₂

Advanced Electronic Materials, EarlyView.
This study demonstrates that alloying Cd₃P₂ with Dirac material Cd₃As₂ significantly enhances its thermoelectric performance. Key improvements include increased carrier mobility, reduced effective mass, and lower deformation potential, resulting in a doubled power factor and improved thermoelectric efficiency, which renders this material applicable for
