We invite you to apply for a Postdoctoral Appointee position within our Materials Science Division (MSD).
The research project focuses on understanding the local electromechanical energy transduction, electronic/ionic transport, and polarization reversal behavior as a function of mechanical, electrical, and thermal stimuli in ferroelectric and multiferroic materials. Although ferroelectrics have been studied for more than several decades, a resurgence of interest has been developed after the recent invention of techniques to create freestanding complex oxide thin films (e.g. PbZrxTi1-xO3), where these behaviors are significantly different from the well-known behavior of epitaxially clamped ferroelectrics. In addition, novel binary oxide (HfO2) ferroelectric materials have shown tremendous technological potential although how these fundamental behaviors are inter-related and can be tuned has remained unknown. The Postdoctoral Appointee will leverage our expertise in these fields to quantitatively investigate these phenomena and correlate electronic, mechanical and thermal energy landscapes in various emerging ferroelectric materials. The Appointee will extensively use different advanced scanning probe microscopy and electronic transport measurement techniques as well as other measurement facilities in the laboratory and user facilities to experimentally study these topics. Besides, the project will also focus on simulations of electronic/ionic transport to decipher the spatial and temporal characteristics of charge and electromechanical coupling in non-linear dielectric materials. The Postdoctoral Appointee will collaborate with scientists and faculties from Argonne and top-ranked universities across the world, who have deep expertise in materials synthesis and condensed matter theory.
Min. Education: Ph.D. (< 3 yrs. since Ph.D.) in Physics/Applied Physics/Materials Science/Electrical engineering.
Candidates should have experience with or an enthusiastic interest in learning new techniques, specifically various modes of scanning probe microscopy and electronic transport measurement. This position will include a variety of physical measurements in the laboratory and at user facilities. A strong, demonstrated commitment to collaborative science is essential.
Results will be published in refereed journals and through oral presentations at meetings, conferences, symposia, and seminars. Up-to-date awareness of developments in the relevant areas of research and excellent knowledge of English (oral and written) and communication skill will be expected.
Prior experience in working with electronic materials, oxide ferroelectrics, and solid-state memory are desired. Familiarity with dielectric materials, piezoelectricity, electrostriction, magnetism, phase-field modeling, energy band diagram, numerical simulation using MATLAB or relevant software will be a plus. A strong experimental and theoretical background in piezoresponse force microscopy, electrostatic force microscopy, electrochemical strain microscopy, microwave impedance microscopy, c-AFM, Kelvin probe microscopy, magnetic force microscopy, and scanning tunneling microscopy is expected. The candidate should also have experience with lock-in amplifier, impedance analyzer, variable temperature probe station, and nanofabrication tools.
The candidate is expected to think and work independently and conduct research in a highly interdisciplinary environment of scientists with backgrounds in electronic engineering, materials science, and physics.
Employer will assist with relocation costs.
