Abstract

The effect of epitaxial stresses on the excess-carrier dynamics and the terahertz radiation spectrum of the In_yGa_1–yAs films have been investigated by optical pump-probe and terahertz time-domain spectroscopy. It has been demonstrated that a In_yGa_1–yAs film with a higher mechanical stress has the shorter excesscarrier lifetime and broader terahertz radiation spectrum.
