Light-induced mobility enhancement in delta-doped GaAs/In0.26Ga0.74As/GaAs quantum wells grown by molecular beam epitaxy on GaAs(001)
(1999)Persistent photoconductivity in 80 angstroms strained GaAs/In0.26Ga0.74As/GaAs quantum wells was investigated by measuring the Shubnikov de Haas and Hall effects at 4.2 K. The quantum wells were grown by molecular beam ...

Superimposed gratings WDM on Ge-doped silica on silicon planar waveguide
(1996)Wavelength-division multiplexed (WDM) devices are becoming increasingly important for fiber-optics communication and sensing systems. Large-channel fanout, low loss, and compatibility with fiber connection, laser sources ...

Time-resolved ultrafast carrier dynamics in as-grown nanocrystalline silicon films: The effect of film thickness and grain boundaries
(2008)In this letter, we have studied transient photoinduced absorption in as-grown nanocrystallinc silicon films with thickness varied from 5 to 30 nm. Effects of quantum confinement (QC) in z-direction and grain boundary ...
