Solid State Oxide Fluorides Kenneth R. Poeppelmeier, Northwestern University, DMR 1005827 The floating zone furnace (shown below at left) is used to grow large crystals needed for property measurement and applications (eg SHG active materials for photonic technologies). A single crystal of Cu2O measuring 1 cm in diameter and 4 cm long is shown at right. Single crystals of Cu2O allow analysis of 3rd harmonic generation (shown below) and exciton behavior.
