Multi‐Vth IGZO FETs Enabled by Continuous‐wave Laser Scanning Annealing for Low Thermal Budget 3D Integration

Advanced Electronic Materials, EarlyView.
A novel strategy is used to fabricate multi‐threshold‐voltage (multi‐Vth) IGZO FETs via continuous‐wave laser scanning annealing (CW‐LSA). By tuning the laser power and scan speed, low, standard, and high Vth values of 0.22, 0.42, and 0.62 V, respectively, were achieved on a single wafer with excellent uniformity (coefficient of variation: 2.17%–6.61%).

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 ...

Environmental Effects on RRAM Cells Based on 2D Halide Perovskite Materials

Advanced Electronic Materials, EarlyView.
RRAM offers high speed, scalability, and low power, positioning it as a next‐generation non‐volatile memory. Two‐dimensional halide perovskites show promise due to tunable optoelectronic properties and flexible processing but suffer from environmental sensitivity. This review examines degradation from humidity, temperature, light, and strain, discusses

Stabilization of Ultrafast Domain Wall Motion by Edge‐Anisotropy Engineering in Ferrimagnetic Nanowires

Advanced Electronic Materials, EarlyView.
Localized laser annealing transforms distorted, edge‐pinned domain‐wall motion in ferrimagnetic Pt/GdFe nanowires into straight, stable, and ultrafast propagation. Experiments and micromagnetic simulations reveal an optimum anisotropy‐engineering window in which moderate edge softening suppresses pinning, whereas excessive anisotropy reduction or ...
