Bias polarity dependent low-frequency noise in ultra-thin AlOx-based magnetic tunnel junctions

Scientific Reports
We exploit bias polarity dependent low-frequency noise (LFN) spectroscopy to investigate charge transport dynamics in ultra-thin AlOx-based magnetic tunnel junctions (MTJs) with bipolar resistive switching (RS).

Coupling Charge‐Regulated Interfacial Chemistry to Electrokinetic Ion Transport in Bipolar SiO2‐Al2O3 Nanofluidic Diodes

Advanced Materials Interfaces
Due to the surface‐dominant nature of electrokinetic ion transport in confined geometries, ionic currents in nanofluidic channels are fundamentally governed by the interfacial chemistry of the constituent substrates.
