Sentences with phrase «semiconductor nanocrystals»
Semiconductor nanocrystals refer to very tiny particles made of special materials that can conduct electricity but only partially. These particles have dimensions in the order of nanometers (billionths of a meter) and are often used in technologies like LEDs, solar cells, and computer chips to control and manipulate light and electrical signals.
