Logical switching using one single molecule

Logic gates, the basic elements of the digital world, can now be built using one single molecule. An example is XOR, with two inputs. If at least one of them is "1," then the output is "1," as well; otherwise, it is 0. These ...

Researchers discover novel quantum effect in bilayer graphene

Theorists at The University of Texas at Dallas, along with colleagues in Germany, have for the first time observed a rare phenomenon called the quantum anomalous Hall effect in a very simple material. Previous experiments ...
