The interest in flexible light-emitting diodes (LEDs) is growing, and some more specific applications can also be found inbiomedical research. Compared to organic LEDs, devices based on inorganic semiconductor LEDs (ILEDs) present theadvantage of high luminance and brightness. Additionally, these ILEDs are much more promising as far as...

The polarization discontinuity across interfaces in polar nitride-based heterostructures can lead to the formation of two-dimensional electron and hole gases. In the past, the observation of these electron and hole gases has been achieved through various experimental techniques, most often by electronic measurements but occasionally by optical...

The interest in flexible micro light-emitting diodes (μLEDs) is growing , and specific applications can be found in biomedical research. For example, in optogenetics stimulations GaN-based μLEDs are good candidates, however, LEDs with reduced dimensions, and improved flexibility (typical dimensions < 50μm and radius of curvature (ROC) down to ~...

The polariton emission in a microcavity is usually measured from the surface, and little is known about the actual role of guided modes below the light cone in air, that can couple to the exciton transition, collect part of the emission and contribute to polariton losses. In this work we investigate a ZnO planar microcavity with mesas. The...
