Resistance Drift of Phase Change Materials Beyond the Power Law

open access: yesAdvanced 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 ...

A High Throughput Platform to Minimize Voltage and Fill Factor Losses

open access: yesAdvanced Energy Materials, EarlyView.
A high‐throughput workflow is developed to determine the Langevin reduction factor in organic photovoltaics autonomously and accurately within seconds. Using UV–Vis spectra, current–voltage curves, and transient absorption kinetics, intrinsic charge absorption cross‐sections are calculated.
