In a historic development, scientists at Pennsylvania State University have successfully used atomically thin materials to create the world's first 2D computer.
This groundbreaking invention represents a major advancement in the development of electronics that are faster, smaller, and use less energy.
Under the direction of Dr Saptarshi Das, the group constructed a computer using complementary metal-oxide semiconductors (CMOS) instead of conventional silicon.
Instead, they created crucial parts for controlling electric current using two distinct 2D materials, tungsten diselenide and molybdenum disulfide.
As devices continue to get smaller: "Two-dimensional materials maintain their exceptional electronic properties at atomic thickness," said Dr Das, meaning the device could offer a promising future.
A lead author and PhD candidate in engineering science, Subir Ghosh stated: “Our 2D CMOS computer operates at low voltages with minimal power consumption”.
Despite its slow speed, the computer uses little power to carry out basic logic operations. This accomplishment sets the stage for potentially lighter, more flexible, and energy-efficient devices in the future.
