InAs Quantum Dots

Indium arsenide (InAs) quantum dots are tiny semiconductor particles, so small that they behave uniquely compared to larger materials. They are only a few nanometers in size—thousands of times thinner than a human hair—and trap electrons in a confined space. This quantum confinement results in discrete energy levels, allowing InAs quantum dots to emit or absorb specific wavelengths of light with high precision. Such properties make them valuable for advanced applications like quantum computing, high-efficiency solar cells, and highly sensitive biological sensors. Their ability to manipulate light and electrons precisely is at the core of their technological importance.
