By housing Weyl fermions, tantalum arsenide
becomes the first experimentally confirmed Weyl semimetal, a metal-like material with exotic and potentially useful features.
chips today are embedded inside the radars' transmit and receive modules.
This is accomplished by growing the solar cell on a gallium arsenide
wafer, flipping it over, then removing the wafer.
"Together, these factors contribute to a growing demand for gallium arsenide
based components, and we have seen no evidence of any let-up in the demand from any of our key customers in the wireless marketplace.
Rosin is used in flux; liquid crystals in all sorts of displays; gallium arsenide
crystals are found in phones, optical networking and wireless LAN; and nickel is used for plating in a host of applications.
Three substances for which there were no previous IARC evaluations have now been evaluated and classified: gallium arsenide
is classified as a Group I human carcinogen, indium phosphide as a Group 2A (probable) human carcinogen, and vanadium pentoxide as a Group 2B (possible) human carcinogen (IARC, in press a).

So they know a little something about things like gallium arsenide
laser systems (eye-safe, 670-nm wavelength lasers, as in the case of the system we'll get to here).
NIST and the National Research Council of Canada (NRC) recently completed a bilateral comparison of routine spectral responsivity calibrations from 250 nm to 1800 nm, using silicon, germanium, and indium gallium arsenide
photodiodes as transfer standards.
Electronic scrap can contain the following hazardous materials: asbestos, cadmium, lead, thallium, beryllium, arsenic, gallium arsenide
, antimony, bismuth, chromium, hexavalent chromium, cobalt, nickel, tin, ,selenium, lithium, PCBs, PCNs, radium bromide tubes, krypton tubes and zinc.
Instead of requiring clean-room facilities (as used in conventional polycrystalline silicone or crystalline gallium arsenide
photovoltaics), cadmium selenide nanocrystals are grown under relatively dirty conditions in a beaker solution.
It also demonstrates SiGe's much lower power consumption than the gallium arsenide
and indium phosphide materials traditionally viewed as necessary for such high-speed operations.
