A hydrogen-related luminescence band in p- and n-type germanium — •Matthias Allardt, Vladimir Kolkovsky, and Jörg Weber — Technische Universität Dresden, 01062 Dresden, Germany

The present work focuses on the photoluminescence (PL) studies in hydrogen-plasma treated p- and n-type germanium. After DC hydrogen plasma treatments in the temperature range 80 - 150 C a new hydrogen-related luminescence band at 723 meV was observed in p- and n-type germanium. The intensity of the band decreases rapidly with temperature and disappears at around 15 K. No shift of the band was detected in the samples with different shallow impurities. The origin of the luminescence band will be discussed.
