The dramatic impact of low dimensional semiconductor structures on
c- rent and future device applications cannot be overstated.
Research over the last decade has highlighted the use of quantum
engineering to achieve p- viously unknown limits for device
performance in research laboratories. The modi?ed electronic
structure of semiconductor quantum structures results in transport
and optical properties, which di?er from those of constituent bulk
materials. The possibility to tailor properties, such as bandgap,
strain, band o?set etc. , of two-dimensional (2D) semiconductors,
e. g. quantum wells, for speci?c purposes has had an extensive
impact on the electronics, which has resulted in a dramatic renewal
process. For instance, 2D structures are today used in a large
number of high speed electronics and optoelectronic appli- tions
(e. g. detectors, light emitting diodes, modulators, switches and
lasers) and in daily life, in e. g. LED-based tra?c lights,
CD-players, cash registers. The introduction of impurities, also in
very small concentrations, in a semiconductor can change its
optical and electrical properties entirely. This attribute of the
semiconductor is utilized in the manifoldness of their app-
cations. This fact constitutes the principal driving force for
investigation of the properties of the impurities in
semiconductors. While the impurities in bulk materials have been
investigated for a long time, and their properties are fairly well
established by now, the corresponding studies of impurities in
quantum wells is a more recent research area.
