The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is ...

Transistors based on ions, as opposed to electrons, offer the promise of bridging the gap between technological and biological systems. Tybrandtet al. present logic gates based on ion bipolar ...

The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is ...

YouTuber Steve Mould has created a great demonstration of computer logic gates using water, tubes, and 3D printed components. This innovative approach ...

Physicists have found a way to make diodes, transistors and logic gates from pure silicon nanowires, without the need for dopants ...

Using this approach, the researchers were able to make ultrafast (less than 100 fs operating time) all-optical XNOR, NOR, AND, XOR, OR and NAND logic gates, as well as a half-adder. And that’s not all ...

Physicists at the University of California, Riverside have received a $2 million research grant to work on "magnetologic gates," a brand new computing building block made from graphene and ...

But high-performance graphene transistors can’t be made using standard fabrication techniques. Building a gate electrode atop graphene damages the carbon sheet and reduces its electron-carrying ...
