A retrospective overview of electrochemical studies of semiconductor nanocrystals (NCs) is given. The electrochemical behavior of monodisperse NCs in a non-aqueous supporting electrolyte can be derived from the electron quasiparticle energy and the electron self-energy. Coulomb blockade can sometimes be observed in Si NCs if the charged NCs are stable. Many NCs, such as Ge, CdS, CdSe, PbS and core-shell...
Synthesis of high quality semiconductor nanocrystals is discussed in this chapter. Although the focus is on the recent progress in synthesis of colloidal semiconductor nanocrystals in non-aqueous solution, there is some review of the historical development of the aqueous and other approaches. Mechanisms for controlling the shape, size, and optical properties of colloidal semiconductor nanocrystals...
The structures of ternary and quaternary silicates are revisited on the basis of the Zintl–Klemm concept and the Pearson's generalised octet rule. The three-dimensional skeletons formed by the Si atoms can be interpreted as if the Si atoms were behaving as Zintl polyanions, adopting the structure of either main-group elements or Zintl polyanions showing the same connectivity. The O atoms are then...
