Acoustic carrier transport in InP-based structures
نویسندگان
چکیده
We demonstrate the ambipolar acoustic transport of optically generated electrons and holes by surface acoustic waves in InGaAsP waveguide structures grown on InP substrates. Transport is detected by monitoring the photoluminescence in the 1400–1500-nm wavelength range emitted by the recombination of the acoustically transported carriers several hundreds of micrometers away from the photoexcitation spot.

Design of a new asymmetric waveguide in InP-Based multi-quantum well laser
Today, electron leakage in InP-based separate confinement laser diode has a serious effect on device performance. Control of electron leakage current is the aim of many studies in semiconductor laser industry. In this study, for the first time, a new asymmetric waveguide structure with n-interlayer for a 1.325 μm InP-based laser diode with InGaAsP multi-quantum well is proposed and theoreticall...
متن کاملCarrier thermalization dynamics in single zincblende and wurtzite InP Nanowires.
Using transient Rayleigh scattering (TRS) measurements, we obtain photoexcited carrier thermalization dynamics for both zincblende (ZB) and wurtzite (WZ) InP single nanowires (NW) with picosecond resolution. A phenomenological fitting model based on direct band-to-band transition theory is developed to extract the electron-hole-plasma density and temperature as a function of time from TRS measu...
متن کاملIndium Phosphide Quantum Dots in GaP and in In0.48Ga0.52P
The growth and structural properties of self-assembled InP quantum dots are presented and discussed, together with their optical properties and associated carrier dynamics. The QDs are grown using gas-source molecular-beam epitaxy in and on the two materials In0.48Ga0.52P (lattice matched to GaAs) and GaP. Under the proper growth conditions, formation of InP dots via the StranskiKrastanow mecha...
متن کاملTime-dependent analysis of carrier density and potential energy in spherical centered defect InGaAs/AlGaAs quantum dot (SCDQD)
Interaction and correlation effects in quantum dots play a fundamental role in defining both their equilibrium and transport properties. Numerical methods are commonly employed to study such systems. In this paper we investigate the numerical calculation of quantum transport of electrons in spherical centered defect InGaAs/AlGaAs quantum dot (SCDQD). The simulation is based on the imaginary time...
