In May, the newsletter of the DOE Office of Science described recent results obtained by the Balandin Group showing acoustic phonon confinement effects in nanoporous arrays. Understanding changes in the acoustic phonon spectrum induced by spatial confinement is important for the fine-tuning of heat propagation in nanometer scale structures and electronic devices. Investigation of the acoustic phonons was made possible by development of the Brillouin-Mandelstam spectroscopy tool at UC Riverside. Fariborz Kargar (pictured to the left) – Research Assistant and PhD Candidate in Balandin group – was the first author of the paper published in Applied Physics Letters.
