Abstract :
We have investigated the high magnetic field effect on the photoexcited electron-hole system in Ge under an uniaxial stress by using optical pump and terahertz probe spectroscopy. The internal transition of magnetoexciton and the cyclotron resonance of the electron and the hole are systematically studied.
