Editing Gallium arsenide (section)

==Safety==
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.<ref>{{cite journal |author1=Shenai-Khatkhate, D V |author2=Goyette, R |author3=DiCarlo, R L |author4=Dripps, G |year=2004 |title=Environment, health and safety issues for sources used in MOVPE growth of compound semiconductors |journal=Journal of Crystal Growth |volume=272 |issue=1–4 |pages=816–821 |bibcode=2004JCrGr.272..816S |doi=10.1016/j.jcrysgro.2004.09.007}}</ref> California lists gallium arsenide as a [[carcinogen]],<ref>{{cite web |date=2008-08-01 |title=Chemicals Listed Effective August 1, 2008 as Known to the State of California to Cause Cancer or Reproductive Toxicity: gallium arsenide, hexafluoroacetone, nitrous oxide and vinyl cyclohexene dioxide |url=http://www.oehha.ca.gov/prop65/prop65_list/080108list.html |publisher=OEHHA}}</ref> as do [[International Agency for Research on Cancer|IARC]] and [[European Chemicals Agency|ECA]],<ref name="Bomhard">{{cite journal |author1=Bomhard, E.
