Pakistan, June 16 -- Engineers at Pennsylvania State University have made a major breakthrough by building the world's first computer entirely from atom-thin, two-dimensional materials-without using any silicon. This development could open the door to smaller, more energy-efficient electronic devices in the future.

According to a study published in Nature, the new computer uses two advanced 2D materials: molybdenum disulfide for n-type transistors and tungsten diselenide for p-type transistors. These transistors are essential components in CMOS (complementary metal-oxide semiconductor) circuits, which power nearly all modern electronics.

"This is the first time a computer has been made completely from 2D semiconductors," said Dr. Saptar...
