Researchers at the Singapore University of Technology and Design (SUTD) have developed a versatile all-electric-controlled valley filter and detailed a solid working design of a valleytronic logic gate that executes the full set of two-input Boolean logics.
The traditional model for generating a logically reversible computer depends on complex circuitries that unavoidably produce large quantities of wasteful bits. The key distinction of the SUTD team's proposed valleytronic-based reversible logic gate is its retention of additional bits of input data in the valley state of the computational output to support logical-reversibility, circumventing complex circuitries and reducing the generation of wasteful bits.
The researchers say this architecture also is more compatible with the expanding industrial and commercial demands for compact smart devices with contracting form factors. "The union of valleytronics, digital information processing, and reversible computing may provide a new paradigm towards the future of ultimately energy-efficient computers with novel functionalities," says SUTD professor Ricky Ang.
