Being zero-dimensional, quantum dots have a sharper density of states than higher-dimensional structures. As a result, they have superior transport and optical properties. They have potential uses in diode lasers, amplifiers, and biological sensors. See more Quantum dots (QDs) - also called semiconductor nanocrystals, are semiconductor particles a few nanometres in size, having optical and electronic properties that differ from those of larger particles as a result of See more Some quantum dots pose risks to human health and the environment under certain conditions. Notably, the studies on quantum dot toxicity … See more Quantum dots are particularly promising for optical applications due to their high extinction coefficient and ultrafast optical nonlinearities with potential applications for developing all … See more The energy levels of a single particle in a quantum dot can be predicted using the particle in a box model in which the energies of states depend on the length of the box. For an exciton inside a quantum dot, there is also the Coulomb interaction between the … See more There are several ways to fabricate quantum dots. Possible methods include colloidal synthesis, self-assembly, and electrical gating. See more In semiconductors, light absorption generally leads to an electron being excited from the valence to the conduction band, leaving behind … See more Quantum dots are theoretically described as a point-like, or zero dimensional (0D) entity.
