Avoid formation of dust and aerosols. Reacts with bases with evolution of hydrogen.

P Obtain special instructions before use. The molten form attacks quartz. Some electronic properties of gallium arsenide are superior to those of silicon. Use personal protective equipment.

,sds GaAs is often used as a substrate material for the epitaxial growth of other III-V semiconductors including indium gallium arsenidealuminum gallium arsenide and others. GaAs devices are relatively insensitive to overheating, owing to their wider energy bandgap, and they also tend to create less noise disturbance in an electrical signal in electronic circuits than silicon devices, especially at high frequencies.

Autumn Safety Kid Safety Looking for safety pic.

CopyrightWafer Technology Ltd. Silicon is a pure element, avoiding the problems of stoichiometric imbalance and thermal unmixing of GaAs.

Do not msde with any dust from mxds semiconductor period. The information in this document is based on the present state of our knowledge and is applicable to the product with regard to appropriate safety precautions. Establish a patent airway. This page was last edited on 27 Novemberat Refractive index n D. Never give anything by mouth to an unconscious person. This method produces crystals with a much lower dislocation density than those produced by any other growth method. I work in university department where they make laser diodes from GaAs wafers and they take every precaution to avoid direct contact to bulk material or GaAs dust.


P Do not eat, drink or smoke when using this product. The Chemistry of the Semiconductor Industry.

Gallium Arsenide Safety.

Do not discharge to sewer systems. Avoid exposure – obtain special instructions before use.

faas Discharge into the environment must be avoided. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace.

If not breathing, give artificial respiration. The above information is believed to be correct but does not purport to be all inclusive and shall be used only as a guide. This low carrier concentration is similar to an intrinsic perfectly undoped crystal, but much easier msss achieve in msdw. These processors were several times faster and several orders of magnitude more radiation proof than silicon counterparts, but were more expensive.

Retrieved from ” https: The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing.


I have searched all day for info on this stuff and although it says there’s nothing on GaAs being toxic, I have found comprehensive and sometimes contradictory information on Arsenic and Gallium compounds being bad. Avoid breathing vapours, mist or gas.


If you do not see the specification you require, please ask for details. Cover skin burns with dry sterile dressings after decontamination The GaAs solar cells, manufactured by Kvant, were chosen because of their higher performance in high temperature environments. Anyone machined this stuff? Silicon has an indirect bandgap and so is relatively poor at emitting light. Accidental release measures 6. In contrast, the absorptivity of GaAs is so high that only a few micrometers of thickness are needed to absorb all of the light.

Dispose of contaminated gloves after ggaas in accordance with applicable laws and good laboratory practices. I work with GaAs wafers, but I’m not a safety guy, so I’m sure there’s a lot more you need to know. In case of skin contact Wash off with soap and plenty of water.

Gallium arsenide – Wikipedia

If swallowed Never give anything by mouth to an unconscious person. I was never given proper gear to separate myself from the dust which can stick to your hands underneath your fingernails. Stability and reactivity
