Monocrystalline metallic nanoparticles are preferable for plasmonic applications, but grow only in polyhedral shapes, which deviate from the predominantly employed spherical shape. Through numerical simulations we have investigated possibilities for

Semiconductor nanowire arrays have been demonstrated as promising candidates for nanoscale optoelectronics applications due to their high detectivity as well as tunable photoresponse and bandgap over a wide spectral range. In the infrared (IR), where

Highly compact, filter-free multispectral photodetectors have important applications in biological imaging, face recognition, and remote sensing. In this work, we demonstrate room-temperature wavelength-selective multipixel photodetectors based on Ga

Nonreciprocal waveguides play an important role in microwave and optical systems. Here we present a new concept for a one-way meta-waveguide: a waveguide that supports a guided mode in one direction while waves traveling in the opposite direction lea

A periodic metagate is designed on top of a boron nitride-graphene heterostructure to modulate the local carrier density distribution on the monolayer graphene. This causes the bandgaps of graphene surface plasmon polaritons to emerge because of eith

GaAsSb nanowire arrays were grown by gold-seeded metalorganic vapor phase epitaxy (MOVPE) and fabricated into photodetector devices. The array photodetectors operate at room temperature with tunable resonance peaks varying with the array geometry. Th

Monocrystalline metallic nanoparticles are preferable for plasmonic applications, but grow preferably in polyhedral shapes which deviate from the pervasive spherical shape. Our simulations show that dimers of octahedral Au nanoparticles have higher f
