Spatio-temporal dynamics of quantum-well excitons (2002)

Zhao, Hui, Don, B. Dal, Moehl, S., Kalt, H., Ohkawa, K., Hommel, D.

We investigate the lateral transport of excitons in ZnSe quantum wells by using time-resolved micro-photoluminescence enhanced by the introduction of a solid immersion lens. The spatial and temporal...

Spin-flip Raman scattering has been used to provide direct experimental evidence that shallow phosphorus acceptors in relaxed ZnSe epitaxial layers grown on GaAs lie at sites of predominantly...

Hepatitis C virus replicative levels and efficiency of genotyping by specific PCR and antibody assay.

Yuki, N, Hayashi, N, Mita, E, Hagiwara, H, Ohkawa, K, Katayama, K, ...

We studied factors which influence the detection of hepatitis C virus genotypes by the group-specific PCR of the sequence within the core region gene and by the newly developed genotype-specific NS4...

Purification and characterization of a rat brain aldehyde dehydrogenase able to metabolize gamma-aminobutyraldehyde to gamma-aminobutyric acid.

Abe, T, Takada, K, Ohkawa, K, Matsuda, M
