Using a wet chemistry process, a collaboration of experts in the United States is now able to manufacture nanometer-sized semiconductor particles called colloidal quantum dots. These nanoscale structures can produce either red, green or blue light.
This is a remarkable achievement, primarily because lasers available... |

A group of researchers in the United States announces the development of a new architecture for quantum-dot light-emitting diodes (QD-LED), devices that can potentially be used to improve computer screens, TVs, standard light sources, and also lasers.
Thanks to these advancements, it may now be possible to create mo... |

A group of investigators at the University of Cambridge announces the development of a new control technique that allows physicists to monitor and influence the most fundamental aspect of any electronic circuit, which is the way in which individual electrons move through it.
The amazing degree of control the team... |

Investigators at the University of Manchester have taken a deep interest in harnessing as much sunlight as possible. They are working with colleagues at several universities in the United Kingdom to achieve this objective, which calls for the creation of new devices for harnessing solar energy. The investigators, bas... |

According to the conclusions of a new scientific investigation, it would appear that the efficiency of existing solar cells could be significantly improved by shrinking the size of light-absorbing particles called quantum dots (QD).
The size of these particles is directly related to its ability to transfer energy... |

Organic light-emitting diodes (OLED) have for some time been touted as the next big thing for the display industry, but thus far they have failed to meet expectations. Now, a company proposes moving on, and shifting research focus from OLED to quantum dot-based displays. One of the main things OLED have going for the... |

Everyone knows that graphene is the one-atom-thick carbon compound that holds the promise to innovate the world of the electronics industry. But very few people know that the insulating equivalent of this material, called graphane, is also right up there in terms of preferences, at least from the scientific community... |

Most modern-day cell phones have at least one camera, which can be used either for visual communications, or for snapping images of the user's surroundings. But one thing that makes these cameras stand out, and not in a good way, is the fact that they produce photos of reduced quality, which almost always look g... |

A team of physicists from the University of Michigan (UM) announce the creation of the world's first atomic-scale map of the promising quantum dots, semiconductors whose excitons are confined in all three spatial dimensions. Quantum dots potentially have the ability to influence a large number of production proc... |

Semiconductors have been the base for modern-day electronics since the first processors appeared, but, for a long time, experts have been trying to make them into structures that not only conduct electricity, but also have their own unique functions. Inspiration for this was drawn from magnets, which, for instance, p... |

Experts from the University of Sheffield, in the UK, the Ecole Normale Superieure, in Paris, France, and the Forschungszentrum Dresden-Rossendorf, in Germany, have recently developed a new type of quantum dot, which is finally able to confirm a long-standing, but never verified theory. The idea states that electrons ... |

The flash storage has been one of the technologies that have undoubtedly changed the face of consumer electronics appliances. It can store a large amount of data on a tiny surface, at the cost of only a few milliwatts. DRAM memory needs permanent refreshing to preserve its contents, but Flash storage can do without p... |
