The previous article examined the concept of logic gates. They can be made from discrete and active electronic components, although today logic gates are available within integrated circuits. In this ...

We report a novel nanodevice using π-conjugated polymers and inorganic semiconductor dual composite P–N junctions single nanowire constructed by PEDOT–PbS–PPY (EPP) nanowire as a two-input OR gate.

Using digital logic gates such as AND, OR, XOR, NOT, NAND, NOR, and XNOR and other related logic functions is often the foundation for defining the relationship between electrical signals and how they ...

A new publication from Opto-Electronic Science; DOI 10.29026/oes.2022.220010 considers optical logic gates in future computers. If you are reading this on your smartphone, its CPU (central processing ...

Arxiv – All-optical integrated circuits for computing and information processing have been pursued for decades as a potential strategy to overcome the speed limitations intrinsic to electronics.

Logic gates are the fundamental building blocks of computers, and researchers at the University of Rochester have now developed the fastest ones ever created. By zapping graphene and gold with laser ...

Logic devices developed by Texas Instruments fully integrate logic-gate and up/down translation functionality from a single power supply, reducing board space by more than 50% versus discrete ...

It may seem a paradox, but in the future tiny computers may dump electronics and return to their mechanical roots. At the macroscale, mechanical computers are fussy and slow, but when your area is ...

DNA is often referred to as the building block of life. Now scientists from Imperial College London have demonstrated that DNA (and bacteria) can be used to create the fundamental building blocks of a ...

Researchers at Politecnico di Milano and CNR-IFN have demonstrated all-optical logic operations in a tungsten disulfide (WS₂) monolayer at rates as high as 10 terahertz, according to a study published ...

If you are reading this on your smartphone, its CPU (central processing unit) is running at its full speed. It is a tiny chip containing billions of the more basic units called logic gates. In the ...
