Abstract
These heterodiamondoids are diamondoids that include heteroatoms in the diamond lattice structure. The heteroatoms may be either electron donating, such that an n-type heterodiamondoid is created, or electron withdrawing, such that a p-type heterodiamondoid is made. Bulk materials may be fabricated from these heterodiamondoids, and the techniques involved include chemical vapor deposition, polymerization, and crystal aggregation. Junctions may be made from the p-type and n-type heterodiamondoid based materials, and microelectronic devices may be made that utilize these junctions. The devices include diodes, bipolar junction transistors, and field effect transistors.
