报告题目：

Materials design and depositions usingHiPIMS

报告摘要：

High power impulse magnetronsputtering  HiPIMS is a deposition technique where ions rather than atomsare utilized for thin film synthesis. This presentation will introduce you tothe physics of the technique, give you a number of examples of its applicationand finally give you examples of the recent research front of the area  

报告人简介：

Ulf Helmersson, professor in Thin FilmPhysics (IFM)

Dr. Ulf Helmersson, head of thePlasma & Coatings Physics division at Linköping University (LiU), hasfocused his research on the complex relationship among thin film growthkinetics, microstructural evolution, and physical properties.  He has madesignificant contributions in all areas.  Ulf started as an electronmicroscopist using the tools to investigate materials physics (i.e.nanoscience) rather than using the microscope as an end in itself.  Earlyin his career he worked on the growth of hard transition metal nitride thinfilms by magnetron sputtering and, in particular, the role of low energy ionirradiation during deposition.  He grew the first man-made artificial"super-hard" material — single crystal TiN/VN superlattices — withhardness comparable to diamond.  The materials choice was prescient sincehe later showed the extreme enhancement in hardness over both of theconstituents, a factor of greater than 2.5 times which is amazing for this property;crystal growth dynamics are also important since optimizations require an interfacialroughness of the order of a few Ångstroms or less.  Such control was unheardof in the mid-1980s (even MBE growth of GaAs/GaAlAs was not superior). Recognizing that any application of this new science would have to involvepolycrystalline films (as wear resistant layers on steel tools, crankshafts,etc.), he spent much of his thesis work and early post-graduate researchunderstanding the growth of these more complex materials where local coherencyand interfacial control is much more difficult and enhanced surface diffusionvia momentum transfer from low-energy ion bombardment must be substituted forhigh growth temperatures which, especially for steel substrates, are notallowed.  His ground-breaking work on super-hard multilayers spawned aglobal industry and his results on the atomistic understanding of ion/surfaceinteractions during the dynamic process of crystal growth is the basis of muchof what we know in this important field today.

As a professor at LiU, Ulf continued his hard-coating work, but alsostarted a new effort in perovskite-structure high temperature superconductorand ferroelectric oxides.  In this case he contributed significantly usinghis atomistic understanding, in combination with high-resolution electron microscopyand physical property measurements, to understand the role of O^-negative ion bombardment during oxide film growth by magnetronsputtering.  His understanding, together with strategies to eithermitigate the effects (when deleterious, i.e. for materials with low bulk atomdisplacement thresholds) or to utilize them for property enhancement, is wellknown in the oxide community.

Over the last several years, Ulf has truly pioneered the development ofHigh Power Impulse Magnetron Sputtering (HiPIMS),the most significant development in physical vapor deposition over the lastdecade.  He co-authored the first paper in that field and, in cooperationwith plasma scientists in Stockholm and Iceland and many other scientists,several extremely important and highly cited papers concerning the science andfunctionality of HiPIMS.

 

Ulf is an important contributor and invitedspeaker to many conferences.  He has regularly attended the InternationalSymposium of the AVS (former American Vacuum Society), the International MetallurgicalCoatings and Thin Films conference in San Diego, The Society of Vacuum Coaters,the International Vacuum Congress, and the Plasma and Surface Engineeringconference in Garmisch-Partenkirchen.  He also teaches short courses through CEIin Europe and the Thin Film physics course at Linköping University.

Ulf has been a mentor for about 20 young scientists that are currentlymaking careers in industry or in academia.  Several have become professorsand many are key scientists at major companies (see list below).  A recentsuccess story is Daniel Lundin, graduated with a PhD in May 2010, who has wonfirst prize within the “Mentor4Research” program (an entrepreneurial programfor young scientists) as well as being selected as number 65 among 101"Supertalents" by the business journal “Veckans Affärer”.  Hehas now, in cooperation with Ulf, founded the company Ionautics AB. Another recent graduate, Erik Wallin, became the first non-American student toreceive a top-level student award (in this case the Russell and Sigurd VarianAward) from the AVS (former American Vacuum Society) in 2008.
