Alternative title: Recent Progress of Floating-Zone Techniques for Bulk Single-Crystal Growth

Description:

This review describes the recent progress of the floating-zone techniques for bulk single-crystal growth. The most crucial point of the crucible-free technique is to keep the molten zone stable. It has been investigated to yield a steeper temperature gradient at the liquid-solid interface along the growth direction and a homogeneous molten liquid along the rotation axis. We overview sev-eral recent achievements starting from the conventional setup, particularly for lamps equipped in horizontal or vertical configurations, tilting mirrors, shielding the irradiation, and filament sizes for the optical-lamp floating-zone furnaces. Also, we describe the recently advancing laser-heated floating-zone furnaces. Throughout the article, we emphasize that the floating-zone technique has been a powerful tool for crystal growth since the 1950s with its roots in the zone-melting method, and it has still been advancing for further materials growth such as quantum materials with modern scientific concepts.
