Description	Infrared reflectance, terahertz transmittance, and microwave resonance measurements show that SrTiO3 films, strained by 1% in biaxial tension by growing them on (110) DyScO3 substrates, undergo a pronounced phonon softening near 270 K. This in-plane soft-mode drives the ferroelectric transition. The appearance of two new low-frequency modes and splitting of the high-frequency TO4 mode provide evidence of an antiferrodistortive phase below 180 K.
