Like photosynthesis in plants: this CPU uses solar energy to ‘run calculations’ without the need for batteries
Penn State researchers built a monolithic 3D chip that runs solely on ambient light without using a battery The chip stacks silicon photovoltaics, MoS₂/WSe₂ complementary logic and graphene chemical sensors within ~50 nm of each other The development also opens the door to larger 2D circuits incorporating some of the same design philosophy in the […]
