HP began production of LEDs that year, using the same gallium arsenide phosphate used by Monsanto. These HP LEDs found their way into very tiny seven-segment LED displays used in HP calculators of ...

The first official LED was created in 1927 by Russian inventor ... of experimenting with materials such as silicon carbide, gallium arsenide, gallium antimonide, indium phosphide, and silicon ...

Most crucially, however, the LED is a vital link between electronics ... the 1962 reports of laser action in gallium-arsenide-based diodes were underpinned by such spectral measurements.

Since the early 1970s, scientists have been promoting gallium arsenide as a faster, more efficient substrate material than silicon for making integrated-circuit chips. However, the vast majority of ...

Materials like indium arsenide (InAs) and gallium antimonide (GaSb ... quantum dots have revolutionized the LED industry. Heterojunction photodetectors exhibit enhanced sensitivity, speed, and ...

In 2001, Motorola developed a technique that places a spongy layer between gallium arsenide and silicon on the same wafer. Combining these two materials yields a higher-speed product at a lower cost.
