Recent developments in the technology of silicon nanocrystals and silicon nanostructures, where quantum-size effects are important, are systematically described including examples of device applications. Due to the strong quantum confinement effect, the material properties are freed from the usual indirect- or direct-bandgap regime, and the optical, electrical, thermal, and chemical properties of these nanocrystalline and nanostructured semiconductors are drastically changed from those of bulk silicon. In addition to efficient visible luminescence, various other useful material functions are induced in nanocrystalline silicon and periodic silicon nanostructures. Some novel devices and applications, in fields such as photonics (electroluminescence diode, microcavity, and waveguide), electronics (single-electron device, spin transistor, nonvolatile memory, and ballistic electron emitter), acoustics, and biology, have been developed by the use of these quantum-induced functions in ways different from the conventional scaling principle for ULSI.

The first two subvolumes III/34Cl and C2 on the Optical Properties of Semiconductor Quantum Structures have been well received by the scientific community. They concentrated on theoretical concepts (chapter 1), experimental methods (chapter 2), III-V semiconductors (chapter 4), I-VII semiconductors (chapter 6), and IV-VI semiconductors (chapter 7) in subvolume Cl. The II-VII materials (chapter 5) have been treated in subvolume C2. The present subvolume III/34C3 finishes the review on optical properties, by adding the chapter 3 on group IV materials. There are exhaustive data on bulk materials including optical properties, starting from diamond C and going over SiC, Si, Ge, to the semimetal grey Sn, and including their alloys—see e.g. Landolt-Börnstein, New Series, Group III, Vol. 41Al 1 and 2, and A2 1 and 2. Silicon is the backbone of the worldwide semiconductor industry. It is an indirect gap material, which seriously hampers its use in light emitting or even laser diodes. There aresome ideas to overcome this problem by forming group IV quantum structures like Si/Ge superlattices or nanocrystals. This hope triggers to a large extend the applied aspects of the research on the optical properties of group IV quantum structures. Though there are also relevant publications on the optical properties of group IV quantum structures involving C or Sn, the by far largest part of work in this field is devoted to the system Si/Ge. Therefore we concentrate here on this system.
