The chapter presents the advances in the chemistry of hypervalent derivatives of selenium and tellurium that have emerged in recent years (usually after 1998). These are based on the inclusion of the discussed compounds into particular subsections, arising from the N‐Ch‐L (A n B m ) coding system, in which N stands for the number of valence electrons associated formally with a central chalcogen atom and L shows the number of ligands (A and B stand for the bonding element). The chapter begins with a brief discussion on the nature of bonding, molecular geometry, basic reactivity and pseudorotation mechanisms in hypervalent selenium and tellurium molecules which can be described as 10‐Ch‐4 and 10‐Ch‐5 and 12‐Ch‐6 species. Next, the unstable hypervalent selenium and tellurium structures detected as reactive intermediates are discussed. The remaining part of the chapter is devoted to the presentation of the chemistry of stable compounds. The isolable derivatives are presented in the following order: selenuranes and telluranes, 10‐Ch‐5 and 12‐Ch‐5 species, 10‐Ch‐6 complexes of perchalcogenuranes with Lewis bases, 12‐Ch‐6 perchalcogenuranes, 12‐Ch‐5 perchalcogenuranes, and 2N‐Ch‐N charged pertelluranes (Ch = Te, N > 6).

The replacement of metal nanocrystal (NC)-based nonvolatile memories (NVMs) with polycrystalline silicon floating-gate memories is very attractive, since they demonstrate superior capability of charge localization and a reduction in cell-to-cell interference. Varying the size (ranging from 15.1 to 55.2 nm) and density (from 5:6 Â 10 11 to 3:2 Â 10 10 cm À2 ) of the metal NC affects the entire memory properties such as the charging/ discharging process, retention characteristic, and charge storage capability. Here, we investigated the effects of the size and density of platinum (Pt) NCs on the aforementioned memory characteristics by fabricating Pt-NC-embedded metal oxide semiconductor (MOS) capacitors using a direct self-assemble method. The flatband voltage shift, a measure of charge storage capability for NC-based NVMs, increased from 5.75 to 13.05 V as the mean size of the NCs was varied from 15.1 to 55.2 nm, which was relatively higher than that of other NC-based NVMs. Our studies revealed that the flatband voltage shift depends on not only the size and density of the NCs, but also the tunneling probability of the electrons, which is closely related to the applied electric field at a tunneling oxide. The relationships among the flatband voltage shift, the size and density of the NCs, and the applied electric field, which are revealed in this study, can be generally applicable to other NVMs based on various metal and semiconducting NCs. #
