Extrinsic and Intrinsic Charge Transfer at Interfaces of Membrane‐Based Oxide Heterostructures
Advanced Electronic Materials, EarlyView.Freestanding oxides have emerged as a new opportunity to tailor oxides outside of the typical epitaxial constraints. We present the fabrication of TiO2‐terminated SrTiO3 membranes via direct growth control. We demonstrate competing ionic and electronic charge transfer in LaAlO3/SrTiO3 bilayers using near ambient pressure XPS.

Influence of Top Electrode Metal on Resistive Switching in Multilayer MOCVD MoS2 Memristors
Advanced Electronic Materials, EarlyView.MoS2 memristors typically use evaporated noble metal electrodes. This study compares Pd, Ni, and Al electrodes and sputtered versus evaporated deposition. Pd is passive, while Ni damages MoS2, yielding poor switching. Sputtered Al enables reproducible ECM‐type switching with 95% yield, whereas evaporated Al forms an interfacial oxide that suppresses ...

Advanced Electronic Materials, EarlyView.ABSTRACT Magnetic 2‐dimensional (2D) van der Waals (vdW) materials have garnered tremendous attention. The vdW ferromagnet Fe5Ge1Te2 has a Curie temperature Tc of ≈ 270 K, which is tailorable by tuning the stoichiometry and the Fe deficiency to reach room temperature.

Advanced Electronic Materials, EarlyView.Composition‐dependent structural evolution in GeXSe1‐X selector‐only memory (SOM) is correlated with device switching behavior. Increasing Ge strengthens network rigidity, suppresses atomic motion, and stabilizes threshold switching, while narrowing the memory window. The revealed structure–property relationship provides a guideline for compositionally

Advanced Electronic Materials, EarlyView.A‐site substitution in Nb2AlC with Fe yields Nb2FeC, a near room‐temperature ferromagnetic MAX phase. Synchrotron‐based spectroscopy and scanning transmission X‐ray microscopy (STXM) with X‐ray magnetic circular dichroism reveal intrinsic bulk ferromagnetism confined to Fe layers, with weak interlayer coupling across Nb2C layer.
