For a long time, scientists have predicted that electrons will flow like water, but this behavior has not been observed. Now, Israeli scientists say in the latest issue of nature that they have observed this strange behavior of electrons for the first time, a new study that promises to spawn low-power electronic devices.
Professor Shahar Ilani, of the Weizmann Institute of Science, said: “The theory suggests that liquid electrons can do things that other types of electrons can’t do. But with clear and conclusive evidence that electrons can indeed form liquids, we hope to see them flow directly. “
To make electrons flow like liquids, a more advanced conductor, such as graphene, a thin layer of carbon thick for a single atom, is needed. But visualizing the flow of electrons in materials such as graphene is not easy, because doing so requires a special technology. The technology must be “powerful” enough to peer into the inside of the material, and at the same time be “gentle” enough not to disrupt the flow of electrons.
The Weizmann team developed the technology, according to the Physicist Sinjustified Network. They developed a nanoscale detector made of carbon nanotube transistors that can image flowing electrons with unprecedented sensitivity. “This technique is at least 1,000 times more sensitive than other methods, allowing us to directly study phenomena that were previously only indirectly studied,” said Dr. Joseph Surpizio. “
Professor Andre Jim’s team at the University of Manchester has developed graphene channels that guide the flow of electrons, similar to those that guide the flow of water. The researchers looked at and imaged them using carbon nanotube transistor detectors, and they observed that the electrons inside graphene flow faster in the center of the channel and more slowly on the wall.
The researchers point out that electrons can flow like liquids, which could lead to new electronic devices, including low-power devices that use fluid power flow to reduce resistance.
“Given the increasing energy consumption of computing centers and consumer electronics and the increasing impact of climate change, it is imperative to find ways to make electrons flow with less resistance,” the researchers explained. “
