Recently, the government has announced that it plans to raise electricity bills, but it would be great if the small appliances in your home no longer need sockets and can run all day long with very little electricity. Scientists recently created a new microelectronic material that can intelligently control how electrons come and go without using much electricity. It’s like giving electronics a smart traffic light, letting them know when to stop and when to go forward. This technology is called “redox gating”. Think of it like a miniature version of a roadblock. Like pressing a magic button, electrons can pass through a door when needed, but not when needed. , the door is closed.
At Argonne National Laboratory, scientists have developed a new type of low-power microelectronic device using a new technology called “redox gating.” This technology controls the flow of electrons at ultra-low voltages, operating as energy-efficiently as synaptic switches in the human brain. This innovation may open a new chapter in energy-saving semiconductors or quantum devices.

The idea came from brainstorming at Argonne National Laboratory, where they discovered that they might get these materials to work with just a tiny bit of voltage—even less than charging a cell phone. The result is like accelerating electrons on a tiny racetrack, making the entire device act like a super-efficient little athlete, achieving high performance with extremely low energy consumption.
The voltage required is lower than charging a mobile phone
“Redox gating” technology is used to regulate electron carriers and control electronic states. The green lines in the figure represent functional molecules that perform redox gating. The low-power nature of this technology is similar to the synaptic switching function in the human brain, as shown by the synapses at the bottom of the illustration.

Today’s electronic devices drive increasingly powerful integrated circuits that are also becoming smaller and smaller. Scientists are working to cram more semiconductor components onto chips to cope with the accelerating trend in microelectronics technology.
Today’s electronic devices drive increasingly powerful integrated circuits that are also becoming smaller and smaller. Scientists are working to cram more semiconductor components onto chips to cope with the accelerating trend in microelectronics technology. The semiconductor device operates like a transistor, switching between a more conductive and insulating state by using voltage to modify the flow of electrons.
This new redox gating strategy can significantly regulate electron flow even at low voltages, providing higher energy efficiency. This also helps avoid system damage, and studies have found that these materials show little performance degradation even with repeated use.
This technology has been published in the latest issue of “Advanced Materials”.
