Thermoelectric materials technology can convert between heat and electricity within a materials construct, but many existing materials contain rare or toxic elements. In a new study on Science, Wenke He and colleagues reported ...
(Phys.org) —Future transistors made of semiconducting single-walled carbon nanotubes (s-SWNTs) have the potential to perform much better than today's transistors. However, when SWNTs are grown in bulk, only about two-thirds ...
In recent years, physicists and material scientists have identified various new materials marked by interesting properties and quantum effects. These materials could prove highly valuable both as platforms to study quantum ...
A new tool that uses light to map out the electronic structures of crystals could reveal the capabilities of emerging quantum materials and pave the way for advanced energy technologies and quantum computers, according to ...
