Dear Reader,

We are now two years into the QUANTIHEAT project and we are sailing at full

speed. There has been a lot of work over the past year and partners have been

working hard on both technical implementation as well as striving towards the best

possible impact of the outcomes. In this respect QUANTIHEAT work has been pre-

sented at various conferences and symposia, where members of our consortium

have presented the project, its main objectives and the current results. After the

set-up of the project during the first year, its technical implementation follows the

original schedule. In 2015, we have seen important progress on the design and char-

acterization of relevant samples using the various techniques available within the

consortium. Throughout this time partners have worked together and shared scien-

tific knowledge, know-how and methodology.

In this 2nd Newsletter, you will read about the progress of our collaborative work

over the last year and you will learn more about our dissemination activities and

exploitation plan. Finally, you will find all important dates regarding upcoming

events.

If you feel that QUANTIHEAT is of particular interest to you, we encourage you to

join the QUANTIHEAT Community and we will keep you informed about the work

progress of the Project.

Enjoy your reading!

Project in a nutshell QUANTIHEAT is a FP7 European project that is aimed at improving our understanding and man-

aging of thermal phenomena at the nanoscale, and at promoting the transfer of new thermal

characterization methods towards Industry. The project started on the 1st December 2013 for

a period of 4 years and gathers 20 partners from Research organizations, Universities, Industry

and National Metrology Institutes.

The main objectives of the project are to:

Define a common terminology for the various thermal characterization instruments

available within the consortium and create reference materials and devices for their

calibration.

Develop new instruments for studying heat transfer at the ultra-local scale, in particular

using Scanning Thermal Microscopy (SThM), the key promising technique for thermo-

physical properties measurements at the nanoscale.

Develop multi-scale thermal models connecting the atomic scale to the macroscopic

scale for interpreting all the phenomena observed.

Apply the developed new metrology tools to representative industrial materials to pro-

pose ways and design laws for improving their properties and/or their manufacturing

processes.

Propose thermal nanomeasurement standards.

During the 1st year (2014), the initial tasks of the project regarding work specification and

methodology were achieved, providing the basis for the other R&D activities:

Measurement and modeling pathways linking techniques available in the Consortium

with materials to be studied in the project were identified.

Design of Experiments (DoE) and inter-comparison exercises to be performed for the

identification of the parameters influencing the SThM measurement and the characteri-

zation of SThM measurement respectively were established.

The past year (2015) was mostly dedicated to the design of passive calibration and test sam-

ples. These will allow us to specify the thermal property measurement by means of SThM. We

also designed active samples for specifying temperature and heat flux SThM measurement.

Characterization of these samples, together with industrial samples, started. A roadmap was

established to plan and organize the characterization of all the project samples that will be

studied with the different available techniques.

VTT, leader of WP3 “Passive test and calibration samples”:

« Calibration and test samples have been fabricated and we have

entered to intensive characterization phase. Timely feedback from

characterization to the design and fabrication is needed for suc-

cessful project and it is delightful to see that there is good colla-

boration/interaction between different partners. We have obtai-

ned the first data sets from test samples and bulk calibration

samples. The work continues now towards one of the project’s key

goals which is to provide characterized reference samples to inves-

tigate the traceability, accuracy and precision of SThM methods. »

CONPART, leader of WP4 “Nanomaterials development”:

« CONPART is excited to be part of the QUANTIHEAT project.

The project gives us access to important know-how and advan-

ced characterization equipment that would otherwise be im-

possible for us to be able to utilize. We believe that this acti-

vity will be of significant help in our endeavor to promote our

unique materials for the electronics industry. »
