Van der Waals Antiferroelectric CuCrPS-Based Artificial Synapse for High-Precision Neuromorphic Computation.

2D van der Waals heterostructure-based artificial synapses have emerged as a compelling platform for next-generation neuromorphic systems, owing to their tunable electrical conductivity and layer-engineered functionality through controlled stacking of 2D materials. In this work, an engineered SnS₂/h-BN/CuCrP₂S₆ van der Waals antiferroelectric field-effect transistor (AFe-FET) is presented that implements synaptic weight modulation through the synergistic interplay of charge trapping dynamics and electric-field-controlled ferroelectric polarization switching. The AFe-FET architecture successfully emulates essential neuroplasticity features, including paired-pulse facilitation, short-term plasticity, and long-term plasticity.

Pressure effect on the magnetism and crystal structure of magnetoelectric metal-organic framework [CHNH][Co(HCOO)].

[CHNH][Co(HCOO)] is the first perovskite-like metal-organic framework exhibiting spin-driven magnetoelectric effects. However, the high-pressure tuning effects on the magnetic properties and crystal structure of [CHNH][Co(HCOO)] have not been studied. In this work, alongside ac magnetic susceptibility measurements, we investigate the magnetic transition temperature evolution under high pressure.

Pressure Control of the Structure and Multiferroicity in a Hydrogen-Bonded Metal-Organic Framework.

Multiferroic materials with the cross-coupling of magnetic and ferroelectric orders provide a new platform for physics study and designing novel electronic devices. However, the weak coupling strength of ferroelectricity and magnetism is the main obstacle for potential applications. The recent research focuses on enhancing the coupling effect via synthesizing novel materials in a chemical route or tuning the multiferroicity in the physical way.
