Outline of Final Research Achievements

Direct detection of low mass dark matter can be realized with low-threshold detector made of low-Z materials. This research program aimed to utilize organic semiconductors for particle detectors and study fundamental properties as a dark matter detector. We developed transistors with organic semiconductors and studied their performances as particle detectors. We succeeded in the detection of heavy nuclei and alpha particles, while more than one order of S/N improvement is still needed to use as a dark matter detector.
