Quantum Dot Fabrication

Quantum dot fabrication involves creating tiny semiconductor particles, typically just a few nanometers in size, that exhibit unique optical and electronic properties. This is achieved through methods like chemical synthesis, where precursors are controlled in a solution to form uniform quantum dots, or physical techniques such as molecular beam epitaxy or lithography, which build quantum dots layer by layer. These processes ensure precise size and composition, allowing quantum dots to emit specific colors when energized. Their customizable properties make them useful in display technologies, solar cells, and biomedical imaging.
