We report a novel and simple fabrication process to realize vertically tapered spot size converters (SSC) on InP photonic integrated circuits. The vertical tapering was achieved via a linewidth controlled local optical dose variation, leading to a gr

Avalanche photodiodes are fabricated and characterized, using a single diffusion fabrication process with the surface patterned by selective area growth prior to diffusion. Raster mapping of the photocurrent near the breakdown voltage is used to char

We report on the effects of Zn-doping using diethylzinc (DEZn) on the growth of In₁₋xGaxAsyP₁₋y quaternary layers (x=0.18–0.41 and y=0.34–0.76) by metalorganic chemical vapour deposition. Independent of the quaternary layer compositions,

We have investigated the quantum efficiency of monolayer MoS2 light-emitting devices through detailed temperature and power-dependent photoluminescence studies and rate equation analysis. The internal quantum efficiency can reach 45 and 8.3% at 83 an

In this work we show that the choice of Ga precursors has a striking effect on the growth kinetics of GaAs nanowires grown by metalorganic vapor phase epitaxy (MOVPE) using the vapor–liquid–solid (VLS) growth mechanism. We investigate the detaile

We have investigated the molecular beam epitaxial growth and characterization of InN nanowires. Detailed optical and electrical transport studies confirm that nondoped InN nanowires can exhibit extremely low ( 15 cm -3 ) residual electron density. Fu
Copper (Cu) and iron (Fe) electrical contacts to gallium arsenide (GaAs) and indium arsenide (InAs) nanowires (NWs) have been fabricated via electrodeposition. For undoped or low carbon-doped (10 17/cm 3), p-type GaAs NWs, Cu or Fe nucleate and grow

We report on the surface passivation of Au-assisted Te-doped GaAs nanowires (NWs) grown by metalorganic vapor phase epitaxy. The electrical properties of individual free standing NWs were assessed using a tungsten nano-probe inside a scanning electro

Wafer bonding using an intermediate layer such as SiO2 is now a standard method for the fabrication of engineered substrates in the semiconductor industry, the prime example being silicon-on-insulator (SOI) substrates. However, direct semiconductor-t
