IWT2023
The IWT2023 workshop (International Workshop on Thermoelectric Materials: from materials chemistry and physics to devices) took place from April 12 to 14, 2023 in Caen. This event aimed to bring together French and Japanese chemists, physicists, and theoreticians from the thermoelectric community. The workshop brought together 75 participants, including a delegation of 12 researchers from Japanese laboratories and around ten researchers in Europe. Three poster prizes were awarded to: Linda Abbassi (LINK, Japan), Sara Passuti (CRISMAT, Caen) and Razvan Burcea (Pprime, Poitiers).
Applications for the Bernard Coqblin thesis prize 2023
Each year, the GIS TE launches a new call for applications for the Bernard Coqblin thesis prize to reward the best thesis on the thermoelectric theme. The price is €500, sponsored by the Moïz company (Grenoble).
To apply for the 2023 Coqblin Prize, the thesis must have been defended between 05/1/2022 and 10/1/2023. The file must consist of an extended CV (CV + list of publications + summary of thesis work) and the thesis defense report. The examination of the files will be carried out by a committee of specialists external to the GIS TE. The award ceremony and presentation of the work of the winner will take place during the next National Thermoelectricity Days. Files should be sent to Christophe Candolfi (christophe candolfi (at) mines-nancy.univ-lorraine.fr).
Do not hesitate to forward this announcement to the young doctors in your teams and to the students who will soon defend their thesis in our field!

Summaries of recent publications in thermoelectricity This section presents summaries of publications extracted from global scientific production in thermoelectricity over the previous 6 – 12 months. These summaries were written by members of the GIS scientific council (CS). The objective is to draw your attention to results deemed “significant” for the theme by these members of the SC. To avoid any confusion, it is specified that the authors of these summaries are not the authors of these publications!
Theme: Devices
Silver nanoparticles: A key to the thermoelectric modules of the future?
Author of the summary: C. Candolfi, Institut Jean Lamour, Nancy
The integration of optimized compounds into thermoelectric (TE) modules faces many challenges to make them efficient and reliable over long periods of time. Among these, bringing TE materials and metallic interconnections into contact is equally important and difficult. These contacts must meet numerous criteria: low electrical and thermal resistance, absence of unwanted chemical reactions and interdiffusion of elements between the TE materials and the other compounds forming the legs, and good mechanical stability. In order to validate all these criteria, diffusion barriers deposited on TE materials are generally associated with a solder serving as “glue” with the metallic interconnections. However, the possible choices for this solder turn out to be very limited: it must in fact remain stable at the temperature on the hot side of the device and the soldering temperature must remain lower than the maximum temperature that the TE materials can withstand so as not to degrade them during this step.
Yin et al. [1] recently proposed using Ag nanoparticles to overcome this problem. The brazing temperature (573 K) remains limited and the layer thus formed remains stable at more than 1000 K. These authors have shown that the devices obtained with different TE compounds (Bi2Te3, PbTe and half-Heusler) are stable while maintaining good performance. Although these results are promising, improvements still seem possible, particularly at the interfaces where temperature drops are observed due to differences in thermal conductivity between the different materials. This leads to a drop in the temperature difference experienced by the TE materials and therefore, to a reduction in the overall performance of the device. Finally, if diffusion barriers were also used by these authors, it remains to be demonstrated that Ag does not diffuse at high temperatures and that the interfaces remain sufficiently stable over time.
