Key Points
Now, researchers at the Massachusetts Institute of Technology (MIT) have developed a new technology that could help us build much more denser circuits on computer chips...
In a study published in Nature Nanotechnology, the researchers document how they made semiconductor transistors using ultrathin 2D materials, each of which was about the thickness of three atoms..
In the past, researchers have tried growing 2D materials elsewhere and transferring them onto a chip or a wafer but this could cause imperfections that can impede the performance of devices...
But at the same time, growing 2D materials directly onto a silicon wafer was challenging because the process typically requires temperatures above 600 degrees Celsius..
To prevent this, the researchers first deposited a very thin layer of passivation material on top of the chip before putting it through the growing process..
