Silicon(IV) Iodide (I4Si) Powder Applications:
Silicon(IV) Iodide (I4Si) Powder is used as a precursor for the synthesis of silicon(IV) amides. It is applied in the fabrication and etching of silicon(IV) in microelectronics.
Selective surface growth of silicon-doped GaAs was achieved by chemical beam epitaxy (CBE) on dry-etched trench structures. Silicon tetraiodide is useful for the process to control metal–semiconductor field-effect transistors (MESFET) and heterostructure field-effect transistors (HFET). Silicon iodide can also be reduced as a source to produce pure silicon and hydrogen iodide.
