Single and multiphoton absorptions in wide band gap semiconductors determine the
functionality of photodetectors, lasers, and light-emitting diodes (LEDs). Although electronic …

There are few materials that are broadly used for fabricating optical metasurfaces for visible
light applications. Gallium phosphide (GaP) is a material that, due to its optical properties …

We demonstrate that a metal–dielectric heterodimer structure can satisfy a nearly ideal first
Kerker condition at a wavelength close to the resonance peak of the dimer, yielding efficient …

Gallium phosphide is a low-loss, high-refractive-index semiconductor considered as a
promising material for active and passive components in modern nanophotonics. In this …

Wide-bandgap semiconductors are widely used in photonic technologies due to their
advantageous features, such as large optical bandgap, low losses, and fast operational …
