Evolution of surface plasmon resonance with slab thickness in hybrid nano-structures of Au/InGaAs slab waveguide
We report on the evolution of the surface plasmon (SP) and waveguide mode (WM) as the core thickness is varied in InGaAs slab waveguides covered by metallic sub-wavelength slit arrays. By comparing transmissio...

Evolutional feature of InAs/GaAs quantum dots with coverages from submonolayer to a few monolayers
In this study, we demonstrate InAs/GaAs submonolayer quantum dots (SQDs) with no wetting layer (WL) formed by using the self-assembling technique. An evolutional feature was observed in the photoluminescence s...

Spectroscopic anisotropy in laterally self-aligned quantum dots
The spectroscopic features observed in laterally self-aligned InGaAs/GaAs quantum dots (QDs) are compared with those in isolated QDs. Though each aligned QD keeps an individual appearance analogous to that of ...

Study of Surface Treatments on InAs/GaSb Superlattice LWIR Detectors
We report on the comparison of mesa sidewall profiles of InAs/GaSb strained-layer superlattice (SLS) detector structures (λ 50% cutoff ≈ 14 μm at V bias = 0 V and T

Structural stability of low temperature grown InGaAs/GaAs heterostructure
InGaAs/GaAs superlattice was grown by molecular beam epitaxy (MBE) on GaAs (100) substrate at low substrate temperature (250°C). The as-grown superlattice sample was then annealed at various temperatures for 1...
