A quantum dot solar cell (QDSC) is a solar cell design that uses quantum dots as the captivating photovoltaic material. It attempts to replace bulk materials such as silicon, copper indium gallium selenide (CIGS) or cadmium telluride (CdTe). Quantum dots have bandgaps that are adjustable across a wide range of energy levels by changing their size.

Alivisatos is the founding scientist of Quantum Dot Corporation, [25] a company that makes crystalline nanoscale tags that are used in the study of cell behavior. [26] (Quantum Dot is now part of Life Technologies.) He also founded the nanotechnology company Nanosys, [27] and Solexant, a photovoltaic start-up that has since restarted as Siva ...
Quantum dots are theoretically described as a point-like, or zero dimensional (0D) entity. Most of their properties depend on the dimensions, shape, and materials of which QDs are made. Generally, QDs present different thermodynamic properties from their bulk materials. One of these effects is melting-point depression.
A quantum dot display is a display device that uses quantum dots (QD), semiconductor nanocrystals which can produce pure monochromatic [a] red, green, and blue light. Photo-emissive quantum dot particles are used in LCD backlights or display color filters. Quantum dots are excited by the blue light from the display panel to emit pure basic ...
He coined the term quantum dots, [4] for demonstrating the first zero-dimensional electronic device that had fully quantized energy states. Reed did research in electronic transport in nanoscale and mesoscopic systems, artificially structured materials and devices, molecular electronics, biosensors and bioelectronic systems, and nanofluidics.
Graphene quantum dots (GQDs) consist of one or a few layers of graphene and are smaller than 100 nm in size. [3][1] They are chemically and physically stable, have a large surface to mass ratio and can be dispersed in water easily due to functional groups at the edges. [4][5] The fluorescence emission of GQDs can extend across a broad spectral ...
Electromagnetically induced transparency. The effect of EIT on a typical absorption line. A weak probe normally experiences absorption shown in blue. A second coupling beam induces EIT and creates a "window" in the absorption region (red). This plot is a computer simulation of EIT in an InAs/GaAs quantum dot.
