Laser diodes are semiconductors that generate light and amplify it using repeated reflection or "optical feedback." Once the ...

On the periodic table, semiconductors (also known as metalloids) crop up along a diagonal line between conductors and insulators. Noble gases such as helium and neon are poor conductors of ...

SR Flip Flop Circuit In this circuit diagram, the output is changed (i.e. the stored data is changed) only when you give an active clock signal. Otherwise, even if the S or R is active, the data will ...

A kind of umbilical cord between different quantum states can be found in some materials. Researchers at TU Wien have now shown that this "umbilical cord" is generic to many materials. It is a ...

This led to the synthesis of n-PBDF, a transparent conducting polymer that can serve both as a conductor and ion-storage material. "This polymer serves dual roles as a transparent conductor and ...
