Films of column IIIA metals (In, Al, and Tl) have been deposited on several different substrates (stainless steel, nickel, copper, and silver) by dissociatively photoionizing the corresponding metal iodide in a uniform electric field. Thin (≲0.2 μm) indium films have been grown on nickel by photoionizing indium monoiodide (InI) vapor with an argon fluoride (ArF) excimer laser at 193 nm. A similar process has resulted in thallium films produced from thallium iodide (TlI) vapor with a high pressure xenon lamp.
