We have promoted researches on carrier interactions in semiconductors, especially putting emphasis on interaction with nuclear spins. We have developed highly-sensitive resistively-detected NMR based on electron spin / nuclear spin interactions atν=2/3 and applied this technique to various studies. The outline of these studies can be found in,

The research results as an extension of these studies can be seen in,

The nuclear polarization and detection can be achieved by using quantum Hall breakdown, too. We use this technique in,

to extend the measurable range in nuclear resonance experiments.
Microscopic studies based on nanoprobe are also very important.

is an example of the output of such a research. We have promoted research on InSb systems as shown below,

As a fundamental research of low-dimensional physics and nanostructure devices, we have the following outputs.

The coherent characteristics of spin systems induced by a pulse sequence are interesting as a novel nuclear resonance technique.
