In quite a few 2D materials, electrons reveal a different quantum feature called “valley,” apart from possessing the qualities of spin and charge. Electrons in numerous 2D materials can survive in properly separated energy minima. The “address” which describes the particular minima the electrons belong to is known as “valley.” “Valleytronics,” which is a new research area, makes use of such “valley address” to encode and process the information.

So far, the progress of valleytronics has been majorly crimped by a dearth of practical designs for a valleytronic-based information processing unit.

Scientists Combine Valleytronics with Digital Information Processing

However, researchers in the Singapore University of Technology and Design (SUTD) have found out a new way of harnessing “valleytronics.” They have unraveled a new avenue towards unique reversible computer by integrating concepts of valleytronics along with that of digital information processing.
By tapping into the non-typical electrical properties of two-dimensional materials, namely topological Weyl/Dirac semimetal thin films and few-layer black phosphorus, the research team from SUTD created a versatile valley filter controlled completely by electric and also showed for the first time, a proper working design of valleytronic logic gate that can perform the complete set of two-input Boolean logics.

As of now, the conventional manner of building a logically-reversible computer depends majorly on complicated circuitries that produce copious amounts of bits that are wasteful. Such complicated, wasteful methods have thwarted reversible computing from acquiring massive industrial and commercial interests.

The unique perceived benefit of reversible logic gate based on valleytronic proposed by SUTD researchers is that the device keeps extra bits of input information in the valley state of computational output to accomplish logical-reversibility.
