Sentences with phrase «quantum confinement»

The team used the CZTS nanocrystal «ink» that results to build a photovoltaic solar cell (pictured) to «confirm that the material works and demonstrate that smaller nanocrystals display «quantum confinement,» a property that makes them versatile for different uses.»

Hollingsworth's breakthrough discovery of «giant» NQDs removed the nanomaterial's problematic photophysical phenomenon of «blinking» and provided an exciting test bed for advancing the understanding of semiconductor physics in the quantum confinement regime.

The Rice - Tokyo team reported an advance in the ability to manipulate light at the quantum scale by using single - walled carbon nanotubes as plasmonic quantum confinement fields.

It seems that the quantum confinement model explains all these observations best.

This leaves two possibilities: quantum confinement and surface states.

For quantum dots smaller than 100 nanometers, the peaks become strongly nonperiodic, indicating a major contribution of quantum confinement.

By contrast, evidence is accumulating in support of the quantum confinement theory.

These could provide the quantum confinement needed for light emission.

Quantum dots are tiny structures, measuring no more than a few nanometres across, which due to quantum confinement can only assume certain, discrete states comparable to the energy level of a single atom.

Nano - patterns created on silicon to confine the defects made the GaAs - on - silicon template nearly defect free and quantum confinement of electrons within quantum dots grown on this template made lasing possible.

Using an engineered strain of Stenotrophomonas maltophilia to control particle size, Lehigh researchers biosynthesized quantum dots using bacteria and cadmium sulfide to provide a route to low - cost, scalable and green synthesis of CdS nanocrystals with extrinsic crystallite size control in the quantum confinement range.

Not exact matches

«We demonstrate that other asymmetric materials, such as asymmetric nanowires, thin films, and quantum dots of a single material can also be high - performance thermal rectifiers, as long as you have lateral confinement,» Ruan said.

They were partly inspired by studies on the confinement of electrons in tiny structures within semiconductors called quantum wells, quantum wires and quantum dots («How to build better lasers», New Scientist, 11 January).

A minute crystallite of silicon of similar dimensions is called a «quantum dot» since there is strong confinement of carriers in all three dimensions.

In effect, these quantum wells (where electrons and «holes» both see a lower energy in the «well» layer, hence the name) use their special properties for the confinement of charge carriers (the electrons and holes) in thin layers at a quantum level.
