In Ga Graphite

The ultra-pure beam of stable flux is a result of the MS crucible concept. Crucibles are made of Pyrolytic Graphite, that is not wetted by Ga or In which guarantees a very low defect density. These cells are preferably used for Nitrides application, where In Ga usually tend to overflow under nitrogen atmosphere with a PBN crucible.

Defence and Strategic Goods List 2019

The Defence and Strategic Goods List is divided in 2 Parts. Part 1 of the List covers defence and related goods, that is goods and technologies designed or adapted for use by armed forces or goods that are inherently lethal. These goods include: military goods, being goods or technology that is designed or adapted for military purposes, including their parts and accessories; and

Engineered Ceramics for Extreme Environments

In this paper a 2D model for Cu(In,Ga)Se-2 (CIGS) solar cells under low solar concentration is described and contrasted with experimental data. Using simulation, the effect of front electric contact design parameters: finger width, finger separation, and number of buses are analyzed for solar concentrations from 1 up to 10 suns.

Chemical vapor deposition of thin films for diffusion

0.59, interstitial nitrides form, while above 0.59, covalent nitrides (such as Si3N4) typically form [Pie96]. The early transition metals (Groups IV, V and VI) have a large enough host lattice to enable formation of interstitial nitrides, where the nitrogen atoms sit on

Protactinium

Protactinium is a chemical element with symbol Pa and atomic number 91. It is a dense, silvery-gray metal which readily reacts with oxygen, water vapor and inorganic acids.It forms various chemical compounds where protactinium is usually present in the oxidation state +5, but can also assume +4 and even +2 or +3 states.

Development Of Thin Films For More Efficient Solar Cells

A crucible heated by radiation of a heater is shielded by one or two thermal shields and its temperature measured by a thermocouple. The source is made up of a metallic chamber with a small orifice, so that a virtually saturated vapour pressure is maintained inside the crucible.

to describe a surface property. A Ga-face surface might be N-terminated if it is covered with nitrogen atoms, but without flipping the crystal it will never be N-faced. It is, however, important to note that the (0001) and (000 1) surfaces of GaN are inequivalent (by convention, the [0001] direction is given by a vector pointing from a Ga atom to a nearest-neighbour N atom).

These paintings are considered a key example of a crucible of artistic styles: Gothic, Islamic and Florentine Trecento. The goal of this work was to use the scientific information provided by a number of experimental techniques – namely EDX, micro-FTIR, micro-Raman and micro-XRD – to assess the dating of the wooden vault, leather preparation and filling fibres.
