Abstract One-dimensional (1D) ZnO nanostructures have been studied intensively and
extensively over the last decade not only for their remarkable chemical and physical …

During the last decade, photonic crystals, also known as photonic microstructures or
photonic bandgap structures, have matured from an intellectual curiosity concerning …

Light-emitting diodes are becoming an increasingly attractive alternative to conventional
light sources due to their small size, high efficiency and long lifetime. Ongoing research is …

Perovskite light-emitting diodes have recently broken the 20% barrier for external quantum
efficiency. These values cannot be explained with classical models for optical outcoupling …

Bright sources of indistinguishable single photons are strongly needed for the scalability of
quantum information processing. Semiconductor quantum dots are promising systems to …

Since the advent of quantum mechanics and the clear demonstration of the existence
of'matter waves', physicists have never failed to take advantage of concepts and theoretical …

The quantum properties of the fluorescence light emitted by diamond nanocrystals
containing a single nitrogen-vacancy (NV) colored center are investigated. We have …

Optical properties of atomically thin transition metal dichalcogenides are controlled by robust
excitons characterized by a very large oscillator strengths. Encapsulation of monolayers …

Electrical operation of InGaN/GaN quantum-well heterostructure photonic crystal light-
emitting diodes (PXLEDs) is demonstrated. A triangular lattice photonic crystal is formed by …

We study the carrier distribution in multi quantum well (multi-QW) InGaN light-emitting
diodes. Conventional wisdom would assume that a large number of QWs lead to a smaller …
