Title: Paul A. Piotrowski: Innovator in Dendritic Web Growth Technology
Introduction
Paul A. Piotrowski is a notable inventor based in Monroeville, PA (US). He has made significant contributions to the field of materials science, particularly in the growth of dendritic web crystals. With a total of 6 patents to his name, Piotrowski's work has advanced the understanding and application of crystalline materials.
Latest Patents
One of his latest patents is titled "Lid for Improved Dendritic Web Growth." This invention features a lid for a susceptor that allows a crystalline material to be melted by induction heating. The design facilitates the formation of a dendritic web of essentially a single crystal, which is pulled through an elongated slot in the lid. The lid includes a pair of round openings adjacent to the ends of the slot, with grooves extending from the outboard surface to the inboard surface. This configuration helps produce uniform radiational heat loss, reducing thermal stresses and enabling the growth of wider webs at a greater withdrawal rate.
Another significant patent is "Web Growth Configuration for Higher Productivity and 100% Feed Rate." This invention introduces a new lid and shield configuration for growing silicon dendritic web crystals. The arrangement consists of multiple spaced-apart shields stacked above a lid with a slot for pulling dendritic web crystals. Each successive shield has a slot slightly larger than the one beneath it, allowing for 100% melt replenishment and increased productivity.
