A new semiconductor with record-high thermal conductivity

Scientists at UCLA, for the first time, experimentally realized a new compound single crystal, boron arsenide (BAs) and explored its thermal conductivity limit when crystals are free of defects. They observed the highest ...

Researchers upend conventional wisdom on thermal conductivity

Scientists have long known that diamond is the best material for conducting heat, but it has drawbacks: It is costly and is an electrical insulator; when paired with a semiconductor device, diamond expands at a different ...

How to cool a smartphone

NUST MISIS scientists have developed composites that conduct heat many times better than their counterparts and are even subject to simple and cheap processing. By using the newly obtained technology in modern electronics, ...

Engineers turn plastic insulator into heat conductor

Plastics are excellent insulators, meaning they can efficiently trap heat - a quality that can be an advantage in something like a coffee cup sleeve. But this insulating property is less desirable in products such as plastic ...

Converting heat into electricity with pencil and paper

Thermoelectric materials can use thermal differences to generate electricity. Now there is an inexpensive and environmentally friendly way of producing them with the simplest tools: a pencil, photocopy paper, and conductive ...

Thermoelectric power generation at room temperature: Coming soon?

Thermoelectric (TE) materials could play a key role in future technologies. Although the applications of these remarkable compounds have long been explored, they are mostly limited to high-temperature devices. Recently, researchers ...
