Supersonic phenomena, the key to extremely low heat loss nano-electronics (Vol. 48 No. 1)

Low-frequency pinned discrete breather when the on-site interaction largely overwhelms the inter-site force.

Supersonic solitary waves in nano-electronics crystals show potentials for electric charge or matter transport and energy storage with extremely low heat dissipation

Freak waves, as well as other less striking localised excitations, occur in nature at every scale. The current theory and models of such waves can be applied to physics and, among others, to oceanography, nonlinear optics and lasers, acoustics, plasmas, cosmological relativity and neuro-dynamics. However, they could also play a significant role at the quantum scale in nano-electronics. In a recent study, the authors performed computer simulations to compare two types of localised excitations in nano-electronics. Their findings, published in a recent study, confirm that such localised excitations are natural candidates for energy storage and transport. These, in turn, could lead to applications such as transistors with extremely low heat dissipation not using silicon.
