Abstract

We applied surface-enhanced Raman spectroscopy (SERS) to the excitation of transversal optical (TO) phonos in strained SiGe. The SERS technique can greatly enhance the Raman signal owing to metal-surface plasmon resonance. Furthermore, the electrical field includes a large amount of z-polarization, which can excite TO phonons. In this study, we evaluated anisotropic biaxial stress state in thin strained-SiGe layer on a Si substrate with the SERS technique.
