Story summary

Pennsylvania State University researchers have built the first silicon-free computer from atom-thin, two-dimensional materials.
The device is a 2D CMOS computer that uses molybdenum disulfide and tungsten diselenide transistors and operates at low power.
They fabricated more than 1,000 transistors using metal-organic chemical vapor deposition.
The work, published in Nature and supported by U.S. research organizations, achieved a 25 kilohertz operating frequency and marks a leap beyond traditional silicon technology.
