Battery-operated electronics users often complain that battery life is too short and the devices generate too much heat, and researchers at the University of Missouri (MU) have developed a material that could solve both problems.

Led by MU's Deepak K. Singh, the team developed a two-dimensional, nanostructured material by depositing a magnetic permalloy on the honeycomb structure template of a silicon substrate.

The new material conducts unidirectional current, and when built into a diode, dissipates significantly less power compared to a conventional semiconducting diode.

The resulting magnetic diode could be used to create new magnetic transistors and amplifiers that dissipate very little power,  boosting the efficiency of the power source in electronic devices.
