Journal ArticleDOI
Comparison of quantum confinement effects on the electronic absorption spectra of direct and indirect gap semiconductor nanocrystals.
TL;DR: The ratio of oscillator strength between direct and indirect structures does not change with size, indicating that zero-phonon transitions are not occurring in the indirect nanocrystals.
Journal Article
Gel Electrophoresis of Gold-DNA Nano-Conjugates
TL;DR: Effective diameters derived from gel electrophoresis measurements are affected with a high error bar as the determined values strongly depend on the method of evaluation, though relative changes in size upon binding of molecules can be detected with high precision.
Journal ArticleDOI
Spin spectroscopy of dark excitons in CdSe quantum dots to 60 T
Ezekiel Johnston-Halperin,David D. Awschalom,Scott A. Crooker,Al. L. Efros,Mervine Rosen,Xiaogang Peng,A. P. Alivisatos +6 more
TL;DR: In this paper, a simple model incorporating angle-dependent Zeeman splitting and bright-dark level mixing in randomly oriented CdSe quantum dots was constructed in quantitative agreement with the data.
Journal ArticleDOI
Quantum confinement and ultrafast dephasing dynamics in InP nanocrystals
Uri Banin,Uri Banin,Giulio Cerullo,Giulio Cerullo,A. A. Guzelian,A. A. Guzelian,Christopher J. Bardeen,Christopher J. Bardeen,A. P. Alivisatos,A. P. Alivisatos,Charles V. Shank,Charles V. Shank +11 more
TL;DR: In this paper, the electronic level structure and dephasing dynamics of InP nanocrystals in the strong quantum-confinement regime are studied by two complementary techniques: nanosecond hole burning and the femtosecond three-pulse photon echo.
Journal ArticleDOI
Exchange interaction in InAs nanocrystal quantum dots
TL;DR: In this article, the size-dependent splitting between the absorbing and the emitting states was investigated in high-quality colloidal InAs nanocrystal quantum dots within the very strong confinement regime and the splitting was assigned to the confinementenhanced electron-hole exchange interaction.
