摘要：

This contribution consists of several parts. In a first part we discuss transport measurements of excitons in Cu2O, their detection by spatially and temporally resolved pump-and-probe beam spectroscopy and by field ionization in a Schottky barrier; in the next one we report on transitions from the Is para to the 2p para exciton state observed in visible pump-IR probe spectroscopy and finally we discuss qualitatively a phase diagram for bulk semiconductors including excitonic Bose-Einstein condensation and the transition to an electron-hole plasma.
