Evidence of cluster dipole states in germanium detectors operating at temperatures below 10 K

Autor: Mei, D. -M., Panth, R., Kooi, K., Mei, H., Bhattarai, S., Raut, M., Acharya, P., Wang, G. -J.

By studying charge trapping in germanium (Ge) detectors operating at temperatures below 10 K, we demonstrate for the first time that the formation of cluster dipole states from residual impurities is responsible for charge trapping. Two planar detect
