Kvanten
Kvanten, also known as quantum dots, are nanoscale semiconductor particles that exhibit unique optical and electronic properties due to quantum mechanical effects. They are typically composed of a core material, such as cadmium selenide, surrounded by a shell material, like zinc sulfide, to improve stability and optical properties. Quantum dots have a size-dependent band gap, meaning their optical and electronic properties can be tuned by adjusting their size. This makes them highly versatile for various applications, including displays, solar cells, and biological imaging.
The quantum confinement effect, where electrons and holes are confined within the nanoscale dimensions of the
Quantum dots have several advantages over traditional semiconductor materials. They offer high color purity, as their
However, quantum dots also have some challenges. Their stability and toxicity are concerns, particularly for cadmium-based
