Topic: Aluminium oxynitride

	aluminum - Hutchinson encyclopedia article about aluminum
		Aluminium is a reactive element which forms stable compounds, so a great deal of energy is needed in order to separate aluminium from its ores, and the pure metal was not readily obtainable until the middle of the 19th century.
		Aluminium was first discovered by Humphry Davy in 1807 and first produced in 1827 by Hans Oersted, who fused potassium with the anhydrous chloride of aluminium in a closed crucible, obtaining the metal in the form of a grey powder.
		Aluminium hydroxide is used as a mordant in dyeing and aluminium chloride as a catalyst in organic reactions.

	Transparent aluminum - Wikipedia, the free encyclopedia
		These are presently produced through the doping of the aluminium with appropriate elements in transparent alumina and in ruby, corundum, sapphire, and related aluminium compounds.
		Traditional photonic bandgaps, based on introducing spatial holes in aluminium, are likewise possible, but these would require the introduction of numerous physical holes with roughly the diameter of the wavelengths of light for which transparence were desired; but such would presumably weaken aluminium structures.
		This is aluminium composed of nanometre scale particles as a solid transparent material, whose colour can be varied by sizing the particles differently.

		As a further alternative, a thin insulating layer of aluminium oxide (Al.sub.2 O.sub.3) could be provided as the layer 201 by subjecting the relatively thick aluminium layer 200 to a conventional oxidation or anodising treatment or by sputter depositing the aluminium oxide onto the relatively thick aluminium layer 200.
		Where the relatively thick layer 200 is an aluminium layer and the relatively thin layer 201 is a layer of aluminium silicide or aluminium oxide, then a chlorine-containing plasma such as boron trichloride (BCl.sub.3) or trichloromethane (CHCl.sub.3) in an argon carrier gas may be used as the anisotropic etchant.
		Further metallisation, again for example aluminium, is deposited and patterned using conventional techniques to define a further electrically conductive region 102 which makes electrical contact with the electrically conductive regions 2' via the conductive plug 80.

		Of prime importance is the nature of the precursor, because it may yield new (oxy)nitride phases unattainable by other synthetic routes.
		The energetics of ionic-covalent, covalent and metallic (oxy)nitride phases are discussed to illustrate the methodology.
		In the frame of density functional theory, we have performed electronic structure calculations on various (oxy)nitrides in order to reach a better understanding of the atomic bonds in the crystal structures and to check whether there is a local nitrogen/oxygen order within the anionic network.

		The problem of tracking small changes in the output wavelngth of laser diodes is addressed using a dual slab waveguide interferometer fabricated from silicon oxynitride.
		Using aluminium as the cathode, the bilayer LED with PDPyDP is considerably more efficient than the corresponding single-layer device or devices with PDVDP or PDPDP as the electron-injection layer.
		Further improvements were found for devices in which a lithium fluoride layer (~ 2nm) was sandwiched between the aluminium electrode and the polymerlayer, and by encapsulating the device with adhesive tape.

		Extraordinary progress in the materials science has broadened the field of potentially useful properties to include electric, magnetic, optic, piezoelectric, mechanic and nuclear applications; and also the nature of raw materials used, including oxides and non-oxides (carbides and nitrides), which are products of the chemical industry.
		Although clay, hydrated silicate aluminium oxide (SiO2 ALO3 H20), originally constituted the primary raw material for making decorative ceramics, tiles, sanitation installations and some refractory materials, the use of new natural and synthetic raw materials such as chipped alumina, silica, alumina silicates or magnesian silicates (cordierite, mullite, steatite) has encouraged the development of technical ceramics.
		Among them, earth-alkalines, carbon and nitrogen have made it possible to develop new phases such as oxynitride, sialon and carbides, which are used in advanced technology ceramics.

		NRA involves probing the sample with light ions accelerated to approximately one tenth of the speed of light and measuring the energies and yields of resulting nuclear reaction products, it is often used instead of back scattering spectrometry when the matrix contains elements heavier than the isotope of interest.
		For many elements, some being oxygen, nitrogen, carbon, aluminium, magnesium and sulphur, the use of a deuterium probing beam (rather than protons or helium) can give enhanced sensitivity and accuracy owing to larger nuclear reaction cross sections, better defined spectral features and less background interference.

		The water vapor has the biggest influence in the gas-phase process due to the production of hydrogen facilitating the heat and mass diffusion between the flame and the droplet.
		Nitrogen is essentially acting in surface reactions with the formation of aluminum nitride (AlN) and oxynitride (AlON) which may completely cover the droplet and stop the gas-phase combustion.
		On the one hand, CO2 burns in the flame, but it is less efficient than H2O because the heat and mass transfer properties are poorer for CO than for H2.
