"I was a student attending an Institute of Physics exhibition in London and they had a gallium phosphide red light emitting diode," he says.
The firm had a keen interest in ramping up production of high efficiency LEDs, which prompted him to look for better ways of growing gallium phosphide layers.
Mitsubishi Electric Corporation (TOKYO:6503), a manufacturer of electrical and electronic equipment, reported today that it is planning to launch two new models of indium gallium phosphide (InGaP) - heterojunction bipolar transistors (HBT) for reception systems in satellite digital radios.
The Lund team first deposits gold particles that are 40 to 70 nanometers in diameter on a small wafer of gallium phosphide. The researchers then place the wafer inside a chamber and feed in a mixture of gases that supplies the raw materials for the trees.
From each of these gold particles emerges a long branch of gallium phosphide. By controlling the size and number of the small gold particles, Samuelson and his colleagues can determine the width of each branch and the density of branches on each trunk.
The amplifier, using advanced indium gallium phosphide (InGaP) semiconductor technology, is offered in a standard ESOP-8 package, which provides excellent heat sinking for demanding thermal environments.
US-based Alpha Industries Inc has introduced what it claims to be the world's first tri-band power amplifier module based on InGaP HBT (indium gallium phosphide heterojunction bipolar transistor) process technology.
Composed of the semiconductor material gallium phosphide, the lenses are transparent to light of visible wave-lengths.
