POSTER CONTEST
The recognition that TEM/STEM and SEM coupled with EELS, EDS and in situ holders can be used as a powerful tool for characterization of materials has been widely established. Recently, the study and development of nanomaterials, a field which is quickly becoming one of the most promising fields of science and technology today, and the development in electron optics, detectors, stage design and fabrication, and recording media has brought an exciting resurgence of interest in TEM.  The goal of this symposium is to bring together a wide variety of researchers with interests in the science, engineering and technological applications to discuss the use of TEM/STEM and SEM techniques on the characterization and modification of properties of materials. Abstracts are solicited in, but not limited to, the following areas involving the use of TEM/STEM and SEM.

SPEAKERS

Dr. Raúl Arenal

ARAID Researcher at The Institute of Nanoscience of Aragon (INA), Spain.

Dr. Raul Arenal received his Ph.D. in Solid State Physics from Univ. Paris-Sud (Orsay, France, 2005) and in 2013, he obtained his Habilitation (HDR) also at this University. From April 2005 to August 2007, he joined the Electron Microscopy Center in Argonne National Laboratory (ANL, USA) as post doctoral fellow. In 2007, he became research scientist (Chargé de Recherches) at the CNRS (France), working at the LEM, CNRS-ONERA (Chatillon, France). From September 2010 to December 2011, he was visiting scientist (sabbatical position) at the Laboratorio de Microscopias Avanzadas (LMA) at the Instituto de Nanociencia de Aragon (INA) of the Universidad de Zaragoza (Spain). Since 2012, Dr. Arenal is on leave from the CNRS, and he is currently ARAID research scientist at the LMA-INA-Universidad de Zaragoza. In addition, since 2007 he is visiting researcher at the ANL (USA). He has published more than 145 papers (H=28 ISI, H=33 Google Scholar) in refereed journals, edited 1 book and published 6 chapters of a book. In 2017, Dr. Arenal has been elected member of the Young Academy of Europe (YAE) and also from this year he has been elected at the board of the YAE. His broad area of research interest lies in electron microscopy focused on materials science and nanoscience: TEM (EELS, HR(S)TEM, electron diffraction, electron tomography). These studies are mainly focused on the growth mechanism, structural and physical (electronic, optical, vibrational, mechanical) properties of nanomaterials based on carbon, boron and nitrogen as well as other nano-structures (in particular, metallic nano-objects for plasmonic/photonic interest). Among his scientific activities, Dr. Arenal is the chair of the HeteroNanoCarb conference series (http://heteronanocarb.org) focused on graphene, NT and related 1D-2D nanomaterials.

Dr. Nasim Alem

Assistant Professor, Dept. of Materials Science and Engineering, Penn State University, USA

Dr. Nasim Alem received her B.S. degree in Metallurgical Engineering from Sharif University of Technology, Tehran, Iran and her M.S. degree in Materials Science and Engineering from Worcester Polytechnic Institute in Worcester, MA. She did her PhD in Materials Science Department at Northwestern University in 2008.  Nasim has been a postdoctoral researcher in the Physics Department at University of California Berkeley and National Center for Electron Microscopy at Lawrence Berkeley National Lab, before joining The Pennsylvania State University as an assistant professor in 2013.

Alem’s PhD research was focused on the nanoscale mechanics and deformation behavior of confined interphases in multilayered metal-ceramic systems where she used transmission electron microscopy to investigate the role of chemistry, and size scale on the plasticity and deformation mechanism at small size scales. Alem’s postdoctoral research was focused on probing the atomic structure of defects and edges and their relaxations in two-dimensional crystals with the utilization of Ultra-high Resolution aberration-corrected transmission electron microscopy.  During her postdoc, Alem also studied the formation, growth and dynamics of defects in two dimensional crystals, i.e. graphene and hexagonal boron nitride under insitu heating and electrical biasing conditions.  Alem joined the Materials Science and Engineering Department at Penn State on March 2013.

Thermoelectric M2O3(ZnO)n nanowires, where M could be In, Ga, Fe, are synthesized using facile solid state diffusion, enabled us to control their defect structure at atomic level. Two kind of defects, planar, parallel to basal wutzite planes, and zigzag, parallel to piramidal planes, facilitate decoupling of electrical and thermal properties. High angle annular dark field (HAADF) imaging of an IGZO nanowire reveled the presence of planar defects, which are monoatomic layers of indium perpendicular to the [002] direction, separated by wurtzite MZnnO(n+1)+  slabs of varying thicknesses. Every O atom on the edges of the MO2  octahedral layers is bonded to three In/Ga atoms and one metal atom within the MZnnO(n+1)+  layer. This creates an inversion domain boundary (IDB) in the wurtzite lattice since the Zn-O bonds on either side of the octahedral layer point with the O atoms toward the In/Ga layer. The MO2  inclusion layer is also associated with a stacking fault, and the wurtzite lattice on one side of the In/Ga layer is translated by ⅓<100>. In some nanowires, partial In/Ga inclusions were also observed. The ends of these partial inclusions are associated with edge dislocations with the dislocation line lying at the leading edge of the MO2 plane. In summary, M2O3(ZnO)n  polytypoid nanowires were converted from pure ZnO nanowires using a simple preferential diffusion process along line defects, which can be used to produce a wide range of ZnO alloys with controllable alloy concentration and layer density. The single layer inclusion growth originates from the surface and propagates though the nanowire by a defect-assisted process. From this study it is apparent that better control of nanometer-scale features could be the key in developing next-generation thermoelectric materials.
