Formation and Stability of Solid Noses During Float Zone Silicon Growth

Crystal Research and Technology, Volume 61, Issue 8, August 2026.
The float zone method is a well‐established way of producing some of the highest purity silicon crystals in the world. However, a common problem is the formation of tiny silicon spikes (called noses) on the feed rod during induction melting. This paper presents a quantitative model of these noses based on the balance between thermal radiation and ...
