Elastic Waves in Nano-Columnar Porous 4H-SiC Measured by Brillouin Scattering

We report measured and calculated frequencies of elastic waves propagating in columnar porous 4H-SiC, an analytically tractable system. The sample was prepared using photo-electrochemical etching followed by mechanical polishing. The frequencies were measured using Brillouin scattering spectroscopy...
