Quantifying biexciton binding energy

A rare spectroscopy technique performed at Swinburne University of Technology directly quantifies the energy required to bind two excitons together, providing for the first time a direct measurement of the biexciton binding ...

Suppressing the Auger recombination process in quantum dots

A Quantum Dot (QD) is a nanometer-sized semiconductor nanocrystal that has unique optical properties such as the ability to emit light in the range of optical frequencies depending on its size. QDs have already been applied ...

Water as a metal

Under normal conditions, pure water is an almost perfect insulator. Water only develops metallic properties under extreme pressure, such as exists deep inside of large planets. Now, an international collaboration has used ...

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 ...
