7. Shape without Structure: An Intriguing Formation Mechanism in the Solvothermal Synthesis of the Phase-Change Material Sb2Te3.

Author

Saltzmann, Tobias, Bornhöfft, Manuel, Mayer, Joachim, and Simon, Ulrich

Subjects
DIFFRACTION patterns, CHEMICAL synthesis, PHASE change materials, NANOELECTROMECHANICAL systems, SCANNING transmission electron microscopy
Abstract

We introduce a novel solvothermal synthesis of individual single crystalline Sb2Te3 micro- and nanocrystals as a model material for phase-change switching. We identified different intermediates along the reaction path to the final Sb2Te3 hexagonal platelets (HPs) and discuss their forming mechanism. By means of nanodiffraction (ND) in a scanning transmission electron microscope we demonstrate that the intermediates follow a hexagonal shape evolution in the amorphous state. In situ nanomanipulator measurements reveal electrical phase-change switching properties of the individual Sb2Te3 hexagonal platelets. [ABSTRACT FROM AUTHOR]

10. [Au14(PPh3)8(NO3)4]: An Example of a New Class of Au(NO3)-Ligated Superatom Complexes.

Author

Gutrath, Benjamin S., Oppel, Iris M., Presly, Oliver, Beljakov, Igor, Meded, Velimir, Wenzel, Wolfgang, and Simon, Ulrich

Abstract

Golden beauty: For the first time a ligand‐stabilized Au14 cluster has been examined. The structure of this superatom complex bears several impressive and unique features, which will further support the understanding of certain guiding principles for molecular‐precision synthesis and functionalization of ultrasmall nanoparticles.
