Technology May Cool The Laptop

02.11.2009
Does your laptop sometimes get so hot that it can almost be used to fry eggs?

New technology may help cool it and give information technology a unique twist, says Jairo Sinova, a Texas A&M University physics professor.

Sinova and colleagues from Hitachi Cambridge Laboratory, Institute of Physics ASCR, University of Cambridge and University of Nottingham have had their research published in the renowned journal Nature Physics.

Laptops are getting increasingly powerful, but as their sizes are getting smaller they are heating up, so how to deal with excessive heat becomes a headache, Sinova explains.

“The crux of the problem is the way information is processed,” Sinova notes. “Laptops and some other devices use flows of electric charge to process information, but they also produce heat.

“Theoretically, excessive heat may melt the laptop,” he adds. “This also wastes a considerable amount of energy.”

Is there a solution?

One approach may be found in Sinova’s research – an alternative way to process information.

“Our research looks at the spin of electrons, tiny particles that naked eyes cannot detect,” the Texas A&M professor explains. “The directions they spin can be used to record and process information.”

To process information, Sinova says, it is necessary to create information, transmit the information and read the information. How these are done is the big question.

“The device we designed injects the electrons with spin pointing in a particular direction according to the information we want to process, and then we transmit the electrons to another place in the device but with the spin still surviving, and finally we are able to measure the spin direction via a voltage that they produce,” Sinova explains.

The biggest challenge to creating a spin-based device is the distance that the spins will survive in a particular direction.

“Transmission is no problem. You can think for comparison that if the old devices could only transmit the information to several hundred feet away, with our device, information can be easily transmitted to hundreds of miles away,” he says. “It is very efficient.”

Talking about its practical application, Sinova is very optimistic. “This new device, as the only all-semiconductor spin-based device for possible information processing, has a lot of real practical potential,” he says. “One huge thing is that it is operational at room temperature, which nobody has been able to achieve until now. It may bring in a new and much more efficient way to process information.”

About research at Texas A&M University: As one of the world’s leading research institutions, Texas A&M is in the vanguard in making significant contributions to the storehouse of knowledge, including that of science and technology. Research conducted at Texas A&M represents an annual investment of more than $582 million, which ranks third nationally for universities without a medical school, and underwrites approximately 3,500 sponsored projects. That research creates new knowledge that provides basic, fundamental and applied contributions resulting in many cases in economic benefits to the state, nation and world.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
