Quantum correlation of channel-confined ions in graphene-based transistors for energy-efficient neuromorphic chips
Authored by Jiahui Zhao, Bo Song & Lei Jiang, published in Communications Materials (2026). This analysis provides key insights into the enterprise implications of this groundbreaking research.
Executive Impact Summary
The rapid progress of artificial intelligence has exposed the inherent limitations of the conventional chip technology, particularly the high energy-consumption, driving the emergence of neuromorphic chips and ionics. Using K+ ion-filled graphene channels, we investigate the mechanism underlying the graphene-based ion transistors by ab initio molecular dynamics simulations. Here we show that graphene electrons enable long-range correlation of confined ions, which provides a basis for the sensitive responses of transistors to the channel ion density (as modulated by a gate voltage). The ON/OFF switching effect specifically results from the competition between π-π stacking and cation-π interaction in the channels with different ion-filling densities. The nonlinear increasing of transport efficiency (i.e., signal amplification effect) is due to the ion density-depended collective oscillation of channel-confined ions. Additionally, resonance between channel-outside and channel-confined ions triggers rapid ion dehydration, enabling the transistor's ultrahigh ion diffusivity. These atomic-level insights as a design principle for the ultralow energy-consumption neuro-morphic chips.
