During the last 25 years (after the growth of the first
pseudomorphic GeSi strained layers on Si by Erich Kasper in
Germany) we have seen a steady accu- mulation of new materials and
devices with enhanced performance made pos- sible by strain.
1989-1999 have been very good years for the strained-Iayer-
devices. Several breakthroughs were made in the growth and doping
technology of strained layers. New devices were fabricated as a
results of these break- throughs. Before the advent of strain layer
epitaxy short wavelength (violet to green) and mid-IR (2 to 5 f.
Lm) regions of the spectrum were not accessi- ble to the photonic
devices. Short wavelength Light Emitting Diodes (LEDs) and Laser
Diodes (LDs) have now been developed using III-Nitride and II-VI
strained layers. Auger recombination increases rapidly as the
bandgap narrows and temperature increases. Therefore it was
difficult to develop mid-IR (2 to 5 f. Lm range) lasers. The effect
of strain in modifying the band-structure and suppressing the Auger
recombination has been most spectacular. It is due to the strain
mediated band-structure engineering that mid-IR lasers with good
per- formance have been fabricated in several laboratories around
the world. Many devices based on strained layers have reached the
market place. This book de- scribes recent work on the growth,
characterization and properties o(compound semiconductors strained
layers and devices fabricated using them.
