Biography:

Daniil Karnaushenko obtained his Dr.-Ing degree in 2016 from the TU Chemnitz (Germany) for his work on shapeable microelectronics. Since 2016 he continued as a senior staff researcher at the IIN (Leibniz IFW Dresden). He was working as a visiting scientist at UT Dallas, Osaka University and Johannes Kepler Universität Linz. His research interests include flexible active electronics, magnetic sensorics, compact self-assembled 3D architectures with a focus on novel microfabrication processes, including self-assembly techniques and shapeable materials technologies.

 

Abstract:

Electronic devices are continually evolving to offer improved performance, smaller sizes, lower weight, and reduced costs, often requiring state of the art manufacturing and materials to do so. An emerging class of materials and fabrication techniques, inspired by self-assembling biological systems shows promise as an alternative to the more traditional methods that are currently used in the microelectronics industry. Mimicking unique features of natural systems, namely flexibility and shapeability, the geometry of initially planar microelectronic structures can be tailored. Heavily relying on cylindrical geometry, fabrication of microwave helical antennas, coils, resonators and magnetic sensors is challenging, when conventional fabrication techniques are applied. Involving novel self-assembly strategies realization of these spatially non-trivial devices in a compact form and with a reduced number of fabrication steps become feasible. This spatial self-assembly process, triggered by an external stimulus, offers a possibility of an improved performance while reducing overall manufacturing complexity of devices and components by harnessing the relative ease in which it can produce mesoscopic 3D geometries such as a “Swiss-roll” architecture. These benefits can lead to tighter a system integration of electronic components including active electronics, capacitors, coils, sensors and antennas with reduced costs fabricated from a single wafer.

 

Biography:

Herbert Gleiter received his Ph.D. in Physics. In 1973, Gleiter became Chair Professor of Materials Science and founded in 1988 today’s Leibniz Institute of New Materials at Saarbruecken, Germany. In 1994, he was appointed Member of the Executive Board of the Research Center Karlsruhe, Germany, and 4 years later he became the Founding Director of the Center’s Institute of Nanotechnology. In 2012 the Chinese Academy of Sciences and the University of Nanjing founded the “Herbert Gleiter Institute of Nanoscience” and appointed him as the Institute’s Founding Director.

Prof. Gleiter’s received more than 40 prizes, seven universities awarded him honorary doctorates. He is a Member of 12 National Academies.of Science and/or Engineering

In the late 70’s he opened the way to a new kind of materials, called today nano-crystalline materials and more recently, he initiated the new field of nano-glasses. It is the attractive perspective of these nano-glasses that they have the potential to provide the basis a new world of glass based technologies.

Abstract:

Today’s technologies are based primarily on utilizing crystalline materials such as metals, semiconductors or crystalline ceramics. The way to a new world of technologies based on non-crystalline materials may be opened by means of nano-glasses. Nano-glasses consist of nanometer-sized glassy regions connected by (nanometer-wide) interfacial regions with atomic and electronic structures that do not exist in melt-cooled glasses. If the size of the nanometer-sized glassy regions is 5 nm or less the volume fraction of these interfacial regions is 50% or above.  Due to their new atomic/electronic structures, the properties of nano-glass differ from the corresponding properties of melt-cooled glasses. For example, FeSc nano-glasses were (at 300K) strong ferro-magnets although the corresponding melt-cooled glasses were paramagnetic. Similarly, the ductility, the biocompatibility, the catalytic properties of nano-glasses were improved by up to several orders of magnitude. Moreover, nano-glasses open the way to new kinds of alloys as they permit the alloying of components that are immiscible in crystalline materials.

Just like in the case of crystalline materials, the properties of which may be changed by varying the sizes and/or chemical compositions of the crystallites, the properties of nano-glasses may be controlled by varying the sizes and/or chemical compositions of the glassy clusters. This analogy opens the  perspective that a new age of technologies - a ”glass age”- may be initiated  by utilizing the new properties of nano-glasses and modifying their properties by varying the sizes and/or chemical compositions of the glassy clusters.
