Abstract
The effect of epitaxial stresses on the excess-carrier dynamics and the terahertz radiation spectrum of the InyGa1–yAs films have been investigated by optical pump-probe and terahertz time-domain spectroscopy. It has been demonstrated that a InyGa1–yAs film with a higher mechanical stress has the shorter excesscarrier lifetime and broader terahertz radiation spectrum.
