A detailed study of the science, engineering and applications of
terahertz technology, based on room-temperature solid-state
devices, which are seen as the key technology for wider
applications in this frequency range. The relative merits of
electronic and optical devices are discussed and new device
principles identified. Issues of terahertz circuit design,
implementation and measurement are complemented by chapters on
current and future applications in communications, sensing and
remote surveillance. Audience: The unique coverage of all aspects
of terahertz technology will appeal to both new and established
workers in the field, as well as providing a survey for the
interested reader.
This Advanced Study Institute on the Electronic Properties of
Multilayers and Low Dimensional Semiconductor Structures focussed
on several of the most active areas in modern semiconductor
physics. These included resonant tunnelling and superlattice
phenomena and the topics of ballistic transport, quantised
conductance and anomalous magnetoresistance effects in laterally
gated two-dimensional electron systems. Although the main emphasis
was on fundamental physics, a series of supporting lectures
described the underlying technology (Molecular Beam Epitaxy,
Metallo-Organic Chemical Vapour Deposition, Electron Beam
Lithography and other advanced processing technologies). Actual and
potential applications of low dimensional structures in
optoelectronic and high frequency devices were also discussed. The
ASI took the form of a series of lectures of about fifty minutes'
duration which were given by senior researchers from a wide range
of countries. Most of the lectures are recorded in these
Proceedings. The younger members of the Institute made the
predominant contribution to the discussion sessions following each
lecture and, in addition, provided most of the fifty-five papers
that were presented in two lively poster sessions. The ASl
emphasised the impressive way in which this research field has
developed through the fruitful interaction of theory, experiment
and semiconductor device technology. Many of the talks demonstrated
both the effectiveness and limitations of semiclassical concepts in
describing the quantum phenomena exhibited by electrons in low
dimensional structures.
