Chips could harvest their own energy using a newly-created alloy

Posted by in categories: computing, mobile phones, sustainability

Why it matters: Electronic devices, which encompass anything from mobile phones to data centers, are notorious energy hogs. One solution could be to harness their heat directly to create a technique for on-chip energy harvesting. The problem has been that none of the few materials able to do this is compatible with current technology in semiconductor fabrication plants. Now, researchers from across Europe have created a germanium-tin alloy that can convert computer processors’ waste heat back into electricity.

A research collaboration in Europe has created a new alloy of silicon, germanium, and tin that can convert waste heat from computer processors back into electricity. It is a significant breakthrough in the development of materials for on-chip energy harvesting, which could lead to more energy-efficient and sustainable electronic devices. Essentially, by adding tin to germanium, the material’s thermal conductivity has been significantly reduced while still maintaining its electrical properties, making it ideal for thermoelectric applications.

The researchers are from Forschungszentrum Jülich and IHP – Leibniz Institute for High Performance Microelectronics in Germany, the University of Pisa, the University of Bologna in Italy, and the University of Leeds in the UK. Their findings made it onto the cover of the scientific journal ACS Applied Energy Materials.

Nearly all AT&T cell customers’ call and text records exposed in a massive breach

Posted by in categories: cybercrime/malcode, mobile phones

The call and text message records from mid-to-late 2022 of tens of millions of AT&T cellphone customers and many non-AT&T customers were exposed in a massive data breach, the telecom company revealed Friday.

AT&T said the compromised data includes the telephone numbers of “nearly all” of its cellular customers and the customers of wireless providers that use its network between May 1, 2022 and October 31, 2022.

The stolen logs also contain a record of every number AT&T customers called or texted – including customers of other wireless networks – the number of times they interacted, and the call duration.

Robust molecule gives organic electronic devices a boost

Posted by in categories: computing, mobile phones

RIKEN chemists have developed a molecule that enhances the performance of organic electronic devices and is also more stable than previous alternatives, raising the chances that it could be used in industrial manufacturing processes (Advanced Materials, “A novel n-type molecular dopant with a closed-shell electronic structure applicable to the vacuum-deposition process”).

Conventional electronic devices are made from hard semiconductors such as silicon, but increasingly organic semiconductor molecules are appearing in devices such as televisions and cell-phone displays that use organic light-emitting diodes (OLEDs).

Stanley Jordan Plays the Periodical Table (Ionization Energies)

Posted by in categories: computing, mobile phones, particle physics, quantum physics

The ionization energy is the amount of energy required to remove a single electron from an atom. If the atom has more than one electron, each one requires more energy than the previous one. The result is a series of increasing energy levels, and in the quantum world these energies correspond to frequencies, as in a musical scale.

This raises an interesting question: if we could hear these frequencies how would they sound? I created an app to find out, and in this video I used my app to share what I learned. As it turns out, the results are quite musical.
