About the Platform

 

The Brillouin – Mandelstam Inelastic Light Scattering Spectroscopy (BMS) Facility is located in the California NanoSystems Institute at UCLA. The unique facility, directed by Professor Alexander Balandin, Department of Materials Science and Engineering, has been built with funding provided by NSF in the framework of the Major Research Instrumentation development project. BMS instrumentation features an integrated inelastic light scattering spectroscopy system with the capability to handle small samples held at cryogenic to room temperature and above. The instrument allows one to measure the energies of various types of elemental excitations, such as phonons and magnons, in different materials and devices. The measured frequencies cover the range from sub-GHz to hundreds of THz, covering the entire range of phonon frequencies from acoustic to optical. The BMS instrument’s capabilities are important for studying the properties of electronic, optical, thermal, mechanical, thermoelectric, magnetic, spintronic, superconducting, and topological materials. The instrumentation also allows one to study biological samples, determining their elastic, optical, and other characteristics.
