Two-dimensional (2D) phase-transition memristors have demonstrated transformative potential for neuromorphic computing, yet challenges like high power consumption, limited endurance, and crystal damage from external ion intercalation persist. Here, we introduce a novel 2D phase-transition memristor leveraging a paradigm-shifting mechanism by exploiting the ultrafast intrinsic Cu+ ion migration within Cu2S. This approach eliminates the need for external ion insertion, significantly reducing crystal damage and enabling exceptional cycling stability with over 400 DC cycles and 500 pulse cycles. The susceptible monoclinic-tetragonal phase-transition induced by intrinsic Cu+ migration achieves an unprecedented SET power consumption of 1 μW at 100 mV, significantly lower in currently reported phase-transition memristors. To further demonstrate the potential of intrinsic ion migration-induced (IIM) memristor, we simulated an IIM memristor crossbar array for image preprocessing in gesture recognition with a high SSIM value of 0.94, showcasing its potential for scalab.e neuromorphic hardware. This work establishes a new paradigm in low-power, high-performance phase-transition memristors, advancing their practical application in next-generation computing. © 2025 Science China Press

Improving elastocaloric effect (eCE) and mechanical properties is the key to developing high-performance eCE cooling materials. In this paper, the metamagnetic shape memory alloys Ni35.5Co13.5Mn35Ti15-x Gdx was successfully prepared by arc melting method, and the effects of Gd substitution for Ti on the martensitic transformation (MT) temperature, phase composition, microstructure, eCE and mechanical properties of the alloys were systematically investigated. With the introduction of Gd elements, transformation temperature shifts to low temperature, and the mechanical properties of the alloy are also enhanced. The maximum compressive strength increased from 980MPa (x=0) to 1142MPa (x=0.9). At room temperature, a large adiabatic temperature change of +13.5/-12.7 K is obtained after loading/unloading, and a constant temperature change of +5.6K/-5.5K is obtained without apparent degradation under the compressive stress of 400 MPa during 61 cycles for Ni36.5Co13.5Mn35Ti14.9Gd0.1 alloy. The underlying mechanism of the enhanced eCE and mechanical properties is also discussed. © 2023, The Authors. All rights reserved.
