Electron Relaxation in Colloidal InP Quantum Dots with Photogenerated Excitons or Chemically Injected Electrons
Femtosecond transient absorption spectroscopy has been used to characterize charge carrier relaxation from the second excited state (1P) to the first excited state (1S) in colloidal indium phosphide (InP) quantum dots (QDs). A three pulse experiment consisting of a visible pump, infrared pump, and white light probe was used to characterize the relaxation of photogenerated excitons, and the role...
متن کاملThe effect of antimony in the growth of indium arsenide quantum dots in gallium arsenide „001..
The effect of an initial saturation coverage of antimony on the growth of indium arsenide quantum dots on gallium arsenide has been studied during metalorganic vapor-phase epitaxy. After depositing one to two bilayers of InAs at 723 K, the samples were quenched, transferred to ultrahigh vacuum, and characterized by scanning tunneling microscopy and x-ray photoelectron spectroscopy. It has been ...
متن کاملRubidium pump-probe spectroscopy: Comparison between ab initio theory and experiment
There has been much interest recently in the effect of the propagation of a laser beam through dilute vapors of alkali metal atoms [1–5] due to their application in laser cooling [6,7], chip-scale atomic clocks and magnetometers [8,9], laser stabilization [10–12], and electromagnetically induced transparency [13]. In order to understand the spectra, several models have been proposed which accur...
متن کاملCharacterization of the ultrafast carrier dynamics of an InAs/InGaAsP quantum dot semiconductor optical amplifier operating at 1.55 μm
Self-assembled quantum dot (QD) Semiconductor Optical Amplifiers (SOAs) are believed to have faster carrier recovery times than conventional multiple quantum well, or bulk SOAs. It is therefore of interest to study the carrier dynamics of QD SOAs to assess their potential as ultrafast nonlinear devices for switching and signal processing. In this work we report experimental characterization of ...
متن کاملExploring size and state dynamics in CdSe quantum dots using two-dimensional electronic spectroscopy.
Development of optoelectronic technologies based on quantum dots depends on measuring, optimizing, and ultimately predicting charge carrier dynamics in the nanocrystal. In such systems, size inhomogeneity and the photoexcited population distribution among various excitonic states have distinct effects on electron and hole relaxation, which are difficult to distinguish spectroscopically. Two-dim...
