SiGe threatens GaAs auto monopoly
Shipments of GaAs chips for automotive radar will
rise over the next few years thanks to the penetration
of this technology into mid-price cars. However,
sales are expected to falter by the middle of the next
decade, due to tough competition from SiGe.
21
Solar cell conversion efficiency
Increasing the conversion efficiency of triple-junction
solar cells will help to cut the cost of this form of
power generation. One approach to higher
efficiencies is to push the bandgaps of the sub-cells
towards the theorectical ideal.
25
The Holy Grail of photonics integration
With hundreds of semiconductor laser designs that
emit at 1550 nm or even 1310 nm, when will the
industry agree on a common platform?
33
InP propels towards a terahertz
DARPA is driving the development of ultra-high-
frequency emitters and receivers based on InP
HEMTs and HBTs that could lead to imaging
16
systems that enable helicopter pilots to navigate
in foggy, smoky and dusty conditions.
38
The exploding LED market
Sales of LED-backlit TVs will rocket over the next
five years, leading to domination of this market.
What are the implications for LED chipmakers and
MOCVD tool manufacturers?
41
Cranking up UV output
A partnership between Asif Khan’s group at the
University of South Carolina and its spin-off, Nitek,
claim to have developed ultra-violet LEDs with a
record output for a single chip.
