Reliable Memristor Crossbar Array Based on 2D Layered Nickel Phosphorus Trisulfide for Energy‐Efficient Neuromorphic Hardware

“…g : 559 cm −1 ) and three out-of-plane A g modes (A (1) 1g : 254 cm −1 , A (2) 1g : 382 cm −1 , A (3) 1g : 588 cm −1 ) can be observed, indicating a high crystallinity of the pristine NiPS 3 nanosheet. [27,28] The NiPS 3 memristor exhibited reproducible bipolar switching properties with a compliance current (I CC ) of 500 μA, as shown in Figure 1d. Under a positive voltage sweep, the memristor switched from the high resistance state (HRS) to the low resistance state (LRS).…”

“…Consistent with previous reports, four in‐plane E g modes ($$E_{\mathrm{g}}^{( 1 )}$$: 130 cm −1 , $$E_{\mathrm{g}}^{( 2 )}$$: 175 cm −1 , $$E_{\mathrm{g}}^{( 4 )}$$: 280 cm −1 , $$E_{\mathrm{g}}^{( 5 )}$$: 559 cm −1 ) and three out‐of‐plane A g modes ($$A_{1{\mathrm{g}}}^{( 1 )}$$: 254 cm −1 , $$A_{1{\mathrm{g}}}^{( 2 )}$$: 382 cm −1 , $$A_{1{\mathrm{g}}}^{( 3 )}$$: 588 cm −1 ) can be observed, indicating a high crystallinity of the pristine NiPS 3 nanosheet.

Unraveling and leveraging in situ surface amorphization for enhanced hydrogen evolution reaction in alkaline media

“…The high-resolution transmission electron microscopy (HRTEM) image of Ru-NiPS 3 NSs showed two different interplanar distances of 0.286 nm and 0.280 nm with a dihedral angle of 62°, corresponding to the (130) and ( 30) planes (Fig. 1b ) 17 . The corresponding selected area electron diffraction (SAED) pattern was indexed to the monoclinic crystal structure along the [001] zone axis (Fig.…”

Machine-learning-accelerated screening of single metal atoms anchored on MnPS3 monolayers as promising bifunctional oxygen electrocatalysts

“…39 Thus, 2D MPS 3 materials have wide applications in Li-ion batteries, field-effect transistors, visible and ultraviolet photodetectors, photoelectrochemical reactions and hydrogen storage. [40][41][42][43][44][45] Inspired by the unique structures, excellent properties and wideranging applications of 2D MPS 3 nanosheets, an interesting question then arises: can we utilize the MPS 3 monolayer as a substrate of SACs for ORR/OER? If so, what kind of TM atom is more favorable and from where does the ORR/OER activity originate?…”
