Al1‐xScxN‐Based Ferroelectric Domain‐Wall Memristors
Advanced Functional Materials, EarlyView.(a) Conductive atomic force microscopy (CAFM) image of the initial state bidomain structure of the Al0.85Sc0.15N (a) showing an enhanced conductivity of the head‐to‐head domain boundary. (b) CAFM image of the same area after application of several −65 V, 1 s voltage pulses showing lower conductivity of the generated tail‐to‐tail domain walls.

Deterministic Writing of Field‐Free and Unipolar Spin‐Transfer Torque Magnetic Random‐Access Memory
Advanced Functional Materials, EarlyView.Deterministic unipolar‐switching STT‐MRAM with field‐free operation is experimentally demonstrated. The device features a compact 4F2 cell architecture using a diode as the access device and a single magnetic tunneling junction. Unlike conventional bipolar switching STT‐MRAM requiring a three‐terminal access transistor in the array, this design offers ...
