Workshop on “thermoelectric properties related to nanostructure and dimensionality in Bi2Te3 nanomaterials”

July 5th-6th, 2012

at GSI Darmstadt, Darmstadt, Germany,

organized by O. Eibl,  N. Peranio, E. Toimil-Molares, R. Hermann, A. Hashibon, J. König, and K. Nielsch

The aims of the workshop are i) to summarize highlights of different Bi2Te3 clusters  of the DFG priority program SPP1386 on nanostructured thermoelectric materials, (ii) to identify limiting mechanisms for the figure of merit, and (iii) to propose promising routes for further  improving ZT.

The workshop will document the advances that have been achieved with respect to (i) sample synthesis, (ii) various characterization methods, (iii) thermoelectric property measurements, and (iv) theoretical modeling.

For reaching this goal, coherent talks and discussion are required on preset topics, to which key notes should be presented. The talks and discussions will be summarized in a book; the organizers of the workshop will strongly pursue this goal.

Speakers, primarily from within the SPP, are encouraged to participate and contribute to the book writing. We will also invite external scientists outside the SPP. Therefore, the date of the workshop was chosen just before the start of the ICT 2012 conference in Denmark.

The preliminary titles of chapters of the book are


-  Preparation of Bi2Te3 nanowires

-  Preparation of Bi2Te3 thin films and superlattices

-  Preparation of Bi2Te3 nanostructured bulk

Structure, Excitations, and Dynamics

-  x-ray and neutron scattering and diffraction

- Imaging, diffraction, and EDX in the TEM

-  Lattice dynamics

-  Excitations analyzed by electron energy-loss spectroscopy

Theory and modelling

-  Modeling the band structure and excitations

-  Modeling thermal transport

-  Modeling TE properties
