Tuning Nanomaterials with Pressure
	Nanomaterials play a high role in today's electronic devices ranging from transistors all the way to lasers and solar-energy conversion devices. A new technique developed at the Lawrence Livermore National Laboratory could allow researchers to manipulate nanomaterials and their fundamental properties only by applying pressure. The experimental rig used by the LLNL researchers uses a cadmium selenide quantum dot solid plac ... [read more >>]

Ultra-Fast, High-Capacity, Non-Volatile RAMs with Quantum Dots
	There are basically two types of random access memories currently marketed all over the world. The Flash memories, most commonly known as portable memory sticks and dynamic random access memories, those used in personal computers. Both types have disadvantages, however they complement each other. For example, Flash memories are non-volatile but they are rather slow at writing data. On the other hand, DRAMs are volatile and have high write ... [read more >>]

Quantum Dots, The Solution for Efficient Solar Cells
	It looks like scientists have finally cracked it! They argue that, by creating a solar cell out of differently sized quantum dots, solar cells could become much more efficient than they currently are. This so-called 'rainbow' design involves arranging quantum dots according to size, so that each one acts on a specific wavelength of the electromagnetic spectrum, thus harvesting most of the power light carries. The un ... [read more >>]

What Is a Quantum Dot?
	I'm sure most of you have heard a few things about quantum dots in science news, however most of these never seem to present what a quantum dot really is. Quantum dots are usually constructed out of semiconductors and routinely studied in electronic devices such as transistors, light emitting diodes or laser diodes. It should be noted that researchers in this field mostly believe that the quantum dots will contribute to the creation o ... [read more >>]

Quantum LEDs - 'Nervous' Tic-Free!
	Solid-state light emitting devices have great versatility, as they produce intense light, a great variety of colors, and can use tunable power sources. On the other hand, they share a dirty little secret. The semiconductor nanostructure tends to emit light in pulses, blinking on and off as the lights in a Christmas tree, which can be pretty annoying and also reduces their range of possible applications. JILA, a collaboration between re ... [read more >>]

Quantum Computers Receive Graphene Quantum Dots Assistance
	Most of the experiments carried out on quantum computer models revolve around the use of gallium arsenide chips to create quantum dots. However, it seems that such a material is not exactly the ideal one when trying to control the spin of an electron inside a quantum dot. The solution for the problems experienced with the gallium arsenide material may be represented in the form of graphene quantum dots, which are much more stable in mainta ... [read more >>]

Pulse Shaping – The Secret Of Tomorrow's Quantum Networks
	The IT industry has worked hard during the time in order to achieve the fastest hardware in the tiniest space possible. Miniaturization was the key, but times are changing and things cannot be pushed beyond anymore, due to the materials' physical limits. Light is promising to offer what matter cannot; it's just a question of time and patience until it is completely tamed. Light has played an important role in networ ... [read more >>]

LED's Outpower QDLED's
	LED, or light emitting diodes, are recognized for their properties of providing low power, color rich, long lived lighting sources, however they might already be out of date, as recently a new type of LED has been designed, by using the quantum-dot technology. It seems that the new quantum-dot LED, or QDLED, is far better than its cousin, thus providing increased clarity and richer colors, and cheaper means to construct them. A quantum ... [read more >>]
