High-temperature deposition

Ignimbrite tuffs welded by their high-temperature deposition caused by the emission of an incandescent cloud of gas and ash from a volcano (a nuee ardente )... 

Therefore, it is quite logical to emphasize low temperature MOCVD (wafer temperature of less than roughly 500°C) of BST tWn films even though the status of the research is still behind that of the high temperature deposition process (wafer temperature of higher than roughly 600°C). Data on films from high temperature CVD is discussed only for reference purposes. 

The liquid source is usually maintained near room temperature, and an inert gas is bubbled through the source. A commonly used source for doping Si is BBrj, which needs a small percentage of O2 in the carrier gas to form B2O3 on the Si surface. Diffusion without O2 blackens the Si In the high temperature deposition furnace ... 

Tungsten ore crystallization can be classified as near-source high-temperature deposits, because wolframite as well as scheelite range on the high-temperature end of the series of minerals crystallizing from hydrothermal liquid. Due to the properties of this liquid, a move to further distant places may also occur.

Very small nuclei that might form in the gas phase can deposit on the substrate and contribute to heterogeneous deposition and accelerate growth. This accounts for blanket deposition (irrespective of substrate) at high supersaturation and also explains the morphological features of high-temperature deposition discussed below. 

Nickel carbonyl [NifCO) is formed by reaction of carbon monoxide with finely divided nickel. The colorless volatile liquid decomposes at high temperatures, depositing pure metallic nickel. In ambient air, nickel carbonyl is relatively unstable and has a half-life of about 100 sec.
