Establish a patent airway. Such good mechanical characteristics also make it a suitable material for the rapidly developing field of nanoelectronics.

CopyrightWafer Technology Ltd. Gallium arsenide GaAs is a compound of the elements gallium and arsenic. The environment, health and safety aspects of gallium arsenide sources such as trimethylgallium and arsine and industrial hygiene monitoring studies of metalorganic precursors have been reported.

The first known gaad use of GaAs solar cells in space was for the Venera 3 mission, launched in Handle in accordance with good industrial hygiene and safety practice. Thermal hazards no data available 9. GaAs diodes can be used for the detection of Agas.

Rinse mouth with water.

GaAs – Gallium Arsenide – Epitaxy Ready Polished Wafers: Wafer Technology

Do not contaminate water, foodstuffs, feed or seed by storage or disposal. For those that might read this down the road, GaAs dust is quite dangerous, at least long term exposure.

From Wikipedia, the free encyclopedia. Uses advised against no data available 1. Show this safety data sheet to the doctor in attendance. In the s, GaAs solar cells took over from silicon as the cell type most commonly used for photovoltaic arrays for satellite applications.


GaAs could be quite dangerous stuff.

The electronic properties of these defects interacting with others cause the Fermi level to be pinned to near the center of the bandgap, so that this GaAs crystal has very low concentration of electrons and holes.

In addition, a Si crystal has a very stable structure and can be grown to very large diameter boules and processed with very good yields. The above information is believed to be correct but does not purport to be all inclusive and shall be used only as a guide. Gallium arsenide single crystals can be prepared by three industrial processes: If inhaled If breathed in, move person into fresh air.

Gallium arsenide

Use proper glove removal technique without touching glove’s outer surface to avoid skin contact with this product. Tighter electrical ranges are available on request. Since the position of the band gap is temperature dependent, it shifts about 0. Safety glasses with side-shields conforming to EN Containers can be triply rinsed or equivalent and offered for recycling or reconditioning.

Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. For this purpose an optical fiber tip of an optical fiber temperature sensor is equipped with a gallium arsenide crystal.

Combined with a high dielectric constantthis property makes GaAs a very good substrate for Integrated circuits and unlike Si provides natural isolation between devices and circuits.

Gloves must be inspected prior to use. Many thanks in advance. Mechanical Specifications Gallium arsenide can be supplied as ingots or ingot sections or as-cut, etched or polished wafers. To my thinking then, if you swallow some of the dust gaws will be in contact with acid in you stomach and this would give off arsenic inside you GaAs does not have a native oxide, does not easily support a stable adherent insulating layer, and does not possess the dielectric strength agas surface passivating qualities of the Si-SiO 2.

For personal protection see section 8. Discharge into the environment must be avoided.

For precautions see section 2. This is a result of higher carrier mobilities and lower resistive device parasitics. Also, the waste needs to be treated as toxic material. Avoid breathing vapours, mist or gas. As a wide direct band gap material with resulting resistance to radiation damage, GaAs is an excellent material for outer space electronics and optical windows in high power applications. For US version, EU version 23 languages and more, please refer to xixisys.

We as supplier shall not be held liable for any damage resulting from handling or from contact with the above product.

Silicon has an indirect bandgap ggaas so is relatively poor at emitting light. HHHF. P Do not handle until all safety precautions have been read and understood.

I was never given proper gear to separate myself from the dust which can stick to your hands underneath your fingernails. An Introduction To Semiconductor Microtechnology 2nd ed. This page was last edited on 27 Novemberat It is also used in gaas manufacture of Gunn diodes for the generation of microwaves. Skin protection Wear impervious clothing.
