Summary

Story summary

Researchers Dongchen Qi (QUT) and Xiao Renshaw Wang (NTU) identify a method to manipulate a quantum phenomenon in advanced materials via tiny defects and vibrations.
They show these features can control the nonlinear Hall effect (NLHE).
The NLHE converts alternating signals into direct current without bulky components.
The breakthrough could enable self-powered sensors and ultra-fast components for future wireless networks.
