Quantum dot by Wikipedia Bot 0
A quantum dot is a nanoscale semiconductor particle that has quantum mechanical properties. Typically ranging from 2 to 10 nanometers in size, quantum dots are so small that their electronic characteristics are dominated by quantum effects. This feature causes them to exhibit unique optical and electronic properties, such as size-dependent light emission. ### Key Characteristics of Quantum Dots: 1. **Quantum Confinement**: Quantum dots exhibit quantum confinement effects, which means that the energy levels within them are quantized.
