In contrast to the common types of non-planar gallium arsenide
nanowires, the researchers' planar nanowire was free from twin defects, which are rotational defects in the crystal structure that decrease the mobility of the charge carriers.
University research groups and semiconductor companies have been racing to develop gallium arsenide
chips that are less costly to make.
Industries is a development stage company that intends to produce gallium arsenide
for sale to manufacturers of integrated circuits, LEDs, diodes and other electronic products.
TriQuint creates standard and custom products using advanced processes that include gallium arsenide
(GaAs), surface acoustic wave (SAW) and bulk acoustic wave (BAW) technologies.
Industry-standard and custom computer-aided design (CAD) tools are used to design gallium arsenide
and high-temperature superconductor devices and circuits, including microwave integrated circuits (MICs), monolithic microwave integrated circuits (MMICs), field effect transistors (FETs) and high electron mobility transistors (HEMTs).
In gallium arsenide
, anti-sites permit electrons to assume intermediate energy levels that aren't otherwise present.
High voltage gallium arsenide
is a tested and proven technology that demonstrates high reliability using existing processes and materials, ideally suited for military and commercial production programs," said Balistreri.
The TGS2302 is a single-pole, double-throw (SPDT) gallium arsenide
switch built for operation in the 4-20 GHz range.
TriQuint Semiconductor designs and manufactures a wide range of high- and low-frequency products across all typical high- and low-power microelectronic ratings using gallium arsenide
, surface acoustic wave (SAW) and bulk acoustic wave (BAW) technologies for many different communications applications including military, network infrastructure, sat-com, wireless (cellular) base stations and fiber optic networks.
Wafers of gallium arsenide
and other semiconductors that can transmit electrons at high speeds and efficiently emit or detect light are costly and fragile.
Products are based on advanced process technologies including gallium arsenide
, surface acoustic wave (SAW) and bulk acoustic wave (BAW).
By delicately parting curtains of electrons, scientists have gazed for the first time into channels on a crystal of the semiconductor gallium arsenide
(SN: 8/16/97, p.
a supplier of gallium arsenide
Marcus and his colleagues at Stanford and the University of California, Santa Barbara fabricated their micrometer-square dot in a sandwich of gallium arsenide
and aluminum gallium arsenide
Compared to conventional RF switches based on gallium arsenide
compound semiconductors, the ML8122MD has a much lower power consumption -- 80% less than that of conventional switches.
