Strongly coupled interface electronic states and interface phonon mode at GaP/Si(001)
Gerson Mette, Kunie Ishioka, Steven Youngkin +3
Ultrafast carrier and phonon dynamics at the buried heterointerface of GaP/Si(001) are investigated by means of two-color pump-probe reflectivity measurements. The carrier-induced…
Low-threshold operation of GaAs-based (GaIn)As/Ga(AsSb)/(GaIn)As W-quantum well lasers emitting in the O-band
Christian Fuchs, Imad Limame, Stefan Reinhard +6
The influence of the growth conditions as well as the device design on the device performance of (GaIn)As/Ga(AsSb)/(GaIn)As "W"-quantum well lasers is investigated. To this purpose…
The influence of growth interruption on the luminescence properties of Ga(As,Sb)-based type II heterostructures
Luise Rost, Jannik Lehr, Milan Maradiya +4
The influence of growth interruption on the luminescence properties of the Ga(As,Sb)/GaAs interface have been studied by continous wave and time resolved photoluminescence spectros…
Coherent optical and acoustic phonons generated at lattice-matched GaP/Si(001) heterointerfaces
Kunie Ishioka, Andreas Beyer, Wolfgang Stolz +4
Thin GaP films can be grown on an exact Si(001) substrate with nearly perfect lattice match. We perform all-optical pump-probe measurements to investigate the ultrafast electron-ph…
Ab initio calculations of the concentration dependent band gap reduction in dilute nitrides
Phil Rosenow, Lars C. Bannow, Eric W. Fischer +4
While being of persistent interest for the integration of lattice-matched laser devices with silicon circuits, the electronic structure of dilute nitride III/V-semiconductors has p…
Sub-picosecond acoustic pulses at buried GaP/Si interfaces
Kunie Ishioka, Avinash Rustagi, Andreas Beyer +5
We report on the optical generation and detection of ultrashort acoustic pulses that propagate in three-dimensional semiconductor crystals. Photoexcitaiton of lattice-matched GaP l…
