Quantum Dots and their Applications

The properties of quantum dots have caused researchers and companies to consider using them in several fields.  The following survey of quantum dot applications introduces many of these uses.

A Survey of Quantum Dot Applications

 

Researchers at Rice University have demonstrated that graphene quantum dots doped with nitrogen can be used as a catalyst to make hydrocarbons from carbor dioxide.

Researchers at Los Alamos National Lab have developed a solar cell that uses a copper indium selenide sulfide quantum dots. Unlike quantum dots containing lead or cadium the copper based quantum dot is non-toxc as well as low cost.

Researchers at the University of Colorado Boulder are investigating the use of quantum dots to treat antibiotic resistant infections.

Using magnetic quantum dots in spintronic semiconductor devices such as memory chips. Spintronic devices are expected to be significantly higher density and lower power consumption because they measure the spin of electronics to determine a 1 or 0, rather than measuring groups of electronics as done in current semiconductor devices.

Researchers are developing  humidity and pressure sensors using graphene quantum dots. These sensors are orginally intented for spaceflight applications because they can function a very low pressure.

Quantum Dots can be used for producing images of cancer tumors. Currently this is used in lab anamials to evaluate the preformance of cancer treatments. 

Quantum dots are being used to produce miniature lasers for use in communications devices. The advantage of these lasers will be high speed data transfer with low power consumption.

Quantum dots can be used in TV or computer displays. Displays using quantum dots should be thinner, lower power than current displays as well as able to be flexible.
