Researchers at the University of California, Berkeley, said: "The semiconductor industry has always believed that 5 nanometers or less is not feasible, so some very small things are not even considered." In recent years, although this statement has been faltering, it is now completely overthrown. Thanks to scientists at the University of California, Berkeley, for discovering carbon nanotubes. Or, because they are usually called graphene.
The transistor has a size of 1 nanometer. In theory, this may further reduce the weight and size of electronic devices. For the background, the current silicon transistor has 20 nanometers. However, it is worth noting that graphene is not the only material used here. The researchers also used molybdenum disulfide to achieve this result.
Using anything, but silicon has a problem with these ultra-small transistors is that at a size of 5nm, it becomes more difficult to pass the material to control the flow of electrons, and the transistor cannot be powered down.
Now, it should be noted that although this is a huge discovery, it is not exactly a very important achievement. As early as 2008, researchers at the University of Manchester used graphene to create a transistor that spans 1 nm with only a few carbon rings. and
