A Novel Growth Technique for Single-Crystal Fibers: The Micro-Czochralski (μ-CZ) Method
Abstract
A novel growth technique (micro-Czochralski method; μ-CZ) for single-crystal fibers is proposed. The technique is a modified Czochralski method in which a single-crystal fiber is pulled from the source melt wetting the surface of a tiny platinum resistance heater. LiNbO3 fibers around 100 μm in diameter and 70 mm in length with either c< 0001> or X< 2\bar{1}\bar{1}0> axes have routinely been pulled at a speed of 0.4-1 mm/sec. The fibers exhibit growth characteristics such as growth striations and growth ridges which are similar to those of as-grown crystal boules.
