Surface waves can help nanostructured devices keep their cool

Due to the continuing progress in miniaturization of silicon microelectronic and photonic devices, the cooling of device structures is increasingly challenging. Conventional heat transport in bulk materials is dominated by ...

Energy-harvesting plastics pass the acid test

A polymer previously used to protect solar cells may find new applications in consumer electronics, reveals a KAUST team studying thin films capable of converting thermal energy into electricity.

White graphene exhibits high defect tolerance and elasticity

Because of their unique physical, chemical, electrical and optical properties, two-dimensional (2-D) materials have attracted tremendous attention in the past decades. After revealing the realistic strength and stretchability ...

Spectral classification of excitons

Ultrathin layers of tungsten diselenide have potential applications in opto-electronics and quantum technologies. LMU researchers have now explored how this material interacts with light in the presence of strong magnetic ...

'Floppy' atomic dynamics help turn heat into electricity

Materials scientists at Duke University have uncovered an atomic mechanism that makes certain thermoelectric materials incredibly efficient near high-temperature phase transitions. The information will help fill critical ...

The age of the Earth's inner core revised

By creating conditions akin to the center of the Earth inside a laboratory chamber, researchers have improved the estimate of the age of our planet's solid inner core, putting it at 1 billion to 1.3 billion years old.
