In the photonic synthetic dimension, the coupling of internal degrees of freedom of photons, such as frequency, spatial mode, and orbital angular momentum, generates extra dimensions in addition to ...

An international collaborative research group has developed a new computational method to visualize the electronic states of aperiodic nanomaterials as band structures through first-principles ...

A new computational method extracts electronic band structures from finite, imperfect, and curved nanomaterials, linking nano-ARPES measurements with theory. (Nanowerk News) Spatially resolved probes ...

Despite a deep understanding of the properties of individual atoms -- the 'ingredients' that make up a crystal -- scientists found that, when they are combined they often display new, unanticipated ...

Researchers at Lund University, Sweden, have grown single continuous GaAs nanowires consisting of segments of pure wurtzite and zincblende phases. Using photoluminescence spectroscopy, they found that ...

Bandgap refers to a region of an element’s crystal’s electronic band structure through which electrons can’t pass. Also referred to as an energy gap, bandgap is a concept in solid-state physics and ...
