“…Figure 1 also includes the refractive index reported in the literature for bulk single-crystal Bi 2,3 and thermally evaporated Bi films. 1,6 It is clearly seen that the data reported in the literature show a high dispersion, although the general trend is similar in all cases including our PLD films. It is worth noting that most of the k values reported in the literature are lower than those of our PLD films.…”

“…Polycrystalline Bi films have usually been prepared by thermal evaporation, 1,[4][5][6][7] although there are some reports on films grown by dc sputtering 8 or the recently developed lowenergy cluster beam deposition. 9 The films grown on substrates held at room temperature are usually found to have columnar-like grains whose size increases as the film thickness increases.…”

Bismuth films are grown at room temperature onto Si substrates by pulsed laser deposition ͑PLD͒. Some films are deposited by dc sputtering ͑DCS͒ for comparison. PLD films are smooth and show micron-sized laminar grains as opposed to DCS films which are rough and show nanometer-sized columnar grains. The optical properties of the films have been studied by means of spectroscopic ellipsometry in the 300-800 nm wavelength interval over a period of six months. The results show that the refractive index of PLD Bi films is independent of the film thickness, thus providing reliable data of the optical constants of Bi films. In addition, it is shown that PLD films exhibit an improved stability to oxidation probably related to their favorable microstructural properties. The thickness dependence of the refractive index in DCS films is related to their surface roughness, the results being improved by pulsed laser melting of these films.
