Bound electron–hole pairs—excitons—are light Bose particles with a mass comparable to or
smaller than that of the free electron. Since the quantum degeneracy temperature scales …

We present an overview of the theoretical background and experimental re sults in the
rapidly develo** field of semiconductor quantum dots-systems 8 6 of dimensions as small …

The observation of vanishing electrical resistance in condensed matter has led to the
discovery of new phenomena such as, for example, superconductivity, where a zero …

The photoluminescence of excitons confined in an electric field tunable coupled AlAs/GaAs
quantum well has been investigated at T≥ 350 mK and magnetic fields H≤ 14 T. In the …

In recent years, the field of self-assembled quantum dots has shown great promise for
nanoscale applications in optoelectronics and quantum computing. Worldwide efforts in both …

Due to the long lifetime of indirect (interwell) excitons, exciton condensation (analogous to
the Bose-Einstein condensation of bosons) is expected to occur in coupled quantum wells …

Carbon is one of the most interesting chemical elements. It not only forms the basis of the
vast kingdom of organic substances but itself forms various crystals and nanostructures. This …

At strong magnetic fields double-layer two-dimensional–electron-gas systems can form an
unusual broken symmetry state with spontaneous interlayer phase coherence. The system …

We present a theoretical and experimental investigation of the effects of a magnetic field on
quasi-two-dimensional excitons. We calculate the internal structures and dispersion …

It is predicted that an excitonic liquid is formed in a system of spatially separated electrons
(e) and holes (h) in a system of two coupled quantum wells. The ground-state energy and …
