  • BULK CRYSTALLINE 4H-SILICON THROUGH A METASTABLE ALLOTROPIC TRANSITION
    Publication number: 20230373794
    Abstract: 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 agglomerates.
