New device suitable to study thermal transport with enhanced sensitivity to in-plane heat flow. Contactless approach suitable for anisotropic materials.
The study of in-plane thermal transport in bulk and low dimensional anisotropic materials is going to be crucial in next years as these materials are incorporated in applications such as electronics, thermoelectrics, and heat management devices.
The current devices and methods are complex, and may be influenced by the shape of the heat source and/or are mostly suitable for electrically insulating samples.
We present a new contactless device and method for studying thermal transport with enhanced sensitivity to in-plane heat conduction, which is based on beam-offset frequency-domain thermoreflectance using a one-dimensional heat source with uniform power distribution. The method has been validated for free standing films, bulk samples (e.g. anisotropic crystals and substrates) and thin films on a substrate.

The Institute of Materials Science of Barcelona (ICMAB) is a Severo Ochoa Centre of Excellence research center which beongs to the Consejo Superior de Investigaciones Científicas (CSIC) and is governed by a Foundation board.
The Institute was set up in 1987 and subsequently, in April 1991, the laboratories were opened at the Campus of the Autonomous University of Barcelona (UAB). It is part of the Barcelona Nanotechnology Cluster in Bellaterra.
The aim of the institute is to carry out research aimed at obtaining and characterising materials of industrial interest. Its activities are based on the synthesis, preparation, crystallization and characterisation of functional high-performance materials and nanomaterials, which in some cases have led to the construction of device prototypes based on these materials.
Studies and improvements both of conventional materials, as well as new molecular, supramolecular, magnetic, superconducting and porous materials etc. are being developed through projects and research contracts. There are currently 9 ERC funded projects at ICMAB.
To develop these activities, at present there are 57 permanent staff among researchers and back up personnel together with 80 non-permanent staff divided into eight researgh groups, one general unit service, and one unit of Scientific and Technological Services.
In 2016 the ICMAB reached the 100.000 citations, and it is currently the first centre, among the CSIC centres, in the Nature Index. Each permanent researcher publishes close to 5 articles per year in Journals with a very high impact factor.
