ALEXANDRIA, Va., Nov. 3 -- United States Patent no. 12,781,389, issued on Nov. 3, was assigned to Carnegie Institution of Washington (Washington).

"Bulk crystalline 4H-silicon through a metastable allotropic transition" was invented by Timothy Strobel (Washington) and Thomas Shiell (Washington).

According to the abstract* released by the U.S. Patent & Trademark Office: "A novel bulk form of 4H-Si, a crystalline allotrope of silicon and a novel method of manufacture. The novel material consists of highly oriented microcrystals of silicon in the 4H structure with no disordered material. The 4H-Si is derived from heating a second novel material Si24 under proper conditions. The allotrope of silicon is produced as bulk, microcrystalline agglo...
