Traditional electronic chips suffer from substantial 'Joule heat', which occurs due to the flow of an electric current producing high temperatures. It is caused by rapid motion and frequent collision among moving charges inside the devices. This severe issue not only causes a large amount of power dissipation, but also hinders the chip's processing speed and limits the number of chips that can be incorporated into appliances.

"We always encounter such problems and inconveniences when using our phones, computers and other electronic devices. We often find that these devices are becoming 'hot' and 'slow', moreover, we need to charge them frequently and have to bring another portable charger sometimes," explained Professor Yang Hyunsoo, the team leader of this research.
