We investigate the spin relaxation of negatively charged excitons in modulation-doped CdTe quantum wells by time-resolved photoluminescence. The charged exciton spin flip process is found to be very sensitive to the excitation energy but not to a change of ...
Multiple refocusing cycles can be used to extract transverse relaxation rates, R2, while homonuclear scalar couplings do not interfere. In this work, I have demonstrated the usefulness of a hybrid sequence, which is a compromise between single and multiple ...
We have investigated carrier spin dynamics in InAs columnar quantum dots (CQDs) by time-resolved photoluminescence (PL) measurement. The CQDs were formed by depositing a 1.8 monolayer InAs seed dot layer and a short-period GaAs/InAs superlattice (SL). The ...
The translational diffusion coeff. of an integral membrane protein/surfactant complex has been measured using a novel pulsed field gradient NMR method. In this new approach, the information about the localization of the mols. is temporarily stored in the f ...
Nuclear magnetic resonance is a powerful nonintrusive technique for measuring diffusion coefficients through the use of pulsed field gradients. The main limitation to the application range of this method is imposed by the relaxation time constants of the m ...
Since many biological processes occur on the μs to ms time scale, internal dynamics on that time scale may well be related to biological functionality. The characterization of internal dynamics is thus an important issue to improve our understanding of the ...
Nuclear magnetic relaxation in the presence of paramagnetic centres has gained increasing interest in recent years partly due to its importance for contrast agents in magnetic resonance imaging. Rational design of new more efficient agents is possible as a ...
A method is proposed to measure the radiation damping rate const. based on the anal. of the nonexponential recovery of the magnetization after inversion. It is applicable when the recovery is dominated by radiation damping rather than by relaxation process ...
Knowledge of proton T-2 relaxation time of metabolites is essential for proper quantitation of metabolite concentrations in localized proton spectroscopy, especially at moderate to long TEs. Although the T-2 relaxation time of singlets, such as that of cre ...
Small diffusion coeffs. can be measured by using populations of singlet states that have a relaxation time const., Ts, which can be much longer than the longitudinal relaxation time, T1. Spatial information can be encoded with pulsed field gradients in the ...
