Reinhard Kaindl
JOANNEUM RESEARCH
Dr. Reinhard Kaindl graduated with a master and a Ph.D. degree in Mineralogy and Petrology from the Karl-Franzens-University Graz, Austria. He worked several years as scientific staff member at the Institute of Earth Sciences of the University Graz. He moved to Institute of Mineralogy and Petrography of the University Innsbruck, Austria and worked there as a research assistant and later scientific staff member. In 2008 he got authority to teach (“venia docendi”) Mineralogy and Petrology at the University Innsbruck. Beside lecturing and supervising thesis he was in charge for the Raman and Infrared spectroscopy labs at the Graz and Innsbruck Universities. Since 2011 he is employed as a senior scientist at JOANNEUM RESEARCH Forschungsgesellschaft at the MATERIALS – Institute for Surface Technologies and Photonics in Leoben and Niklasdorf, Austria.
His research interests are deposition, research and development of amorphous and crystalline metal, carbon and nitrogen thin films and coatings; graphene and graphene-related materials; characterisation of nano-, micro- and macro-materials by vibrational Raman and IR-spectroscopy, ellipsometry, and indentation, scratch and tribology experiments including computer simulations.
He has published more than 120 articles with more than 1900 citations and a h-index of 22 and gave 12 invited lectures. He coordinated and participated on more than 15 national and international basic and applied R&D projects funded by the Austrian Science Foundation (FFG) and Science Fund (FWF), as well as Horizon 2020 programs like MNT-ERA.NET. In an ongoing project he cooperates with the Institute of Metal Research of the Chinese Academy of Sciences in Shenyang. The project topics covered carbon nano- and 2D-materials, 3D metal printing (Selective Laser Melting) and functional coatings on metal, oxide and plastic substrates at room and high temperatures. Beside that he ran contract research projects about nanodiamonds, diamond-like carbon, thermal conductivity, insulating, conducting and coloured thin films and oxides for companies and institutions in Austria and neighbouring countries.

Abstract

For state of the art and high-power electronics metals or ceramics are commonly used as heat spreading materials of choice. While the performance is adequate at the moment, the power density and therefore heat production in electronic circuits will increase tremendously in the next decades or even years. Today diamond is being used for demanding thermal assemblies. While diamond outperforms all known ceramics and metals in thermal dissipation capabilities its difficult workability increases the price for this material to a non-economic level. Low-cost high conductive materials are necessary for the next generation of electronic devices. The demands on the thermal management of the products increase almost day-per-day, conventional printed circuit boards, even equipped with metal cores, will soon reach their physical limits.
In the collaborative research project GRATEC scientists and engineers from Austria, Sweden and China synthesize graphene- and carbon nanotube (CNT)-based materials, deposit and functionalize heat-spreading films by industrial scalable processes like Aerosol Jet printing and plasma-treatment and characterize the films by sophisticated methods. The goal is thermal management of the next generation of electronics with a performance comparable to copper. The novel materials are expected to overcome the insufficient thermal performance of printable conductors in their targeted field of application in the automotive industry, specifically high-performance front-lighting systems.
The presentation will show results of light, scanning electron and atomic force microscopic and Raman spectroscopic investigations of aerosol jet and inkjet printed and functionalized nanocarbon films on aluminium substrates and first calculated and measured thermal performance data.
