Understanding Quantum Dots in Electrodynamics
Quantum dots (QDs) are nanoscale semiconductor particles whose electronic properties lie between those of bulk semiconductors and discrete molecules. Their unique optoelectronic properties make them a subject of great interest in the field of electrodynamics. Quantum dots are particularly known for their quantum confinement effect, where the electron and hole are confined in all three spatial dimensions.
The Electrodynamics of Quantum Dots
At the heart of quantum dot technology lies the principle of electrodynamics. When a quantum dot absorbs a photon, an electron gets excited to a higher energy level, leaving behind a hole. The interaction between this electron-hole pair, known as an exciton, is crucial for understanding the optical and electronic properties of QDs. The size and composition of the quantum dot dictate the energy levels and, consequently, the color of light they emit or absorb. This tunability through size adjustment is a key feature distinguishing them from bulk materials.
Applications of Quantum Dots
