Physical Sciences: Tools and Techniques (PST)

PST.1: Phase Microscopy

Recent technological developments in the re-shaping of imaging waves (whether using apertures in real space or phase plates in reciprocal space) are enabling the latest generations of detectors to be used in powerful new ways. This session will cover new developments in phase-related imaging techniques across electron microscopy, x-ray imaging and allied techniques. Submissions relating to either the introduction of phase shifts in the imaging process (such as in holography and interferometry, or with vortex beams and new probe shapes) or the retrieval of phases from collected data (including ptychography, TIE, Lorentz microscopy and differential phase contrast etc.) are welcome.

    • Doug Bonn (The University of British Columbia, CA)

      Doug Bonn is an experimental physicist working in the field of quantum materials at the University of British Columbia. His main research in unconventional superconductivity, has involved infrared spectroscopy, magnetic measurements, high-field transport measurements, microwave spectroscopy, and scanning tunnelling microscopy/spectroscopy. This began with PhD work (McMaster University, 1989) that used infrared spectroscopy to study the superconducting gap of the newly-discovered high temperature superconductors. Later at UBC with Walter Hardy he developed superconducting microwave resonators that led to three distinct discoveries of long-term importance to the study of these and other unconventional superconductors. The most prominent was precision measurements of the London penetration depth in YBa2Cu3O7-x which revealed a linear temperature dependence of the superfluid density. This was a controversial and pivotal measurement that shifted the field to identifying these materials as d-wave superconductors. The techniques also yielded the discovery of long-lived quasiparticles in the superconducting state and revealed the importance of critical fluctuations. This work included a team effort with Walter Hardy and Ruixing Liang on crystal growth of high-purity, high temperature superconductors that fueled much collaborative research in Canada, the United States, and Europe. In recent years, his work has moved into developing and employing scanning tunneling microscopy (STM) techniques, and coincided with the emergence of the iron pnictides, a new family of high temperature superconductors. Work on these materials, especially LiFeAs, has identified an S+ pairing state using quasiparticle interference, and has highlighted the importance of inelastic tunneling processes when using STM to study these materials.

PST.5: Diffraction Techniques and Structural Analysis

Structural analysis and nanoscale crystallography using electron diffraction and related methods has undergone a renaissance in recent years. There have been a series of major developments in recent years that have transformed the field, including: the advent of remarkably sensitive, almost noise-free, cameras and detectors; the introduction of automated data collection and big data processing (e.g. machine learning); and the availability of dedicated software that enables robust and reliable structure determination from electron data. This has led to an explosion of interest across a wide range of materials and life sciences in using these techniques to (i) solve crystal structures not amenable to more conventional x-ray diffraction and (ii) to use the high spatial resolution of the microscopes to reveal hitherto unseen micro- and nano-structure using 4D scanning methods, acquiring diffraction patterns at every real space probe position. This session highlights the progress made in this area using both scanning electron microscopy (with techniques such as EBSD (2D and 3D), ECCI, TKD and (scanning) transmission electron microscopy such as 4D-STEM, SED, SPED, PED, CBED, SCBED, HRTEM, time-resolved diffraction and ptychography. We would also encourage submission of papers from complementary fields such as atom probe tomography and scanning transmission x-ray microscopy.

PST.6: In Situ and In Operando Microscopy

In order to understand dynamic processes in functional materials they have to be studied under relevant environmental conditions and driving forces. Significant developments in instrumentation has brought various stimuli (e.g. temperature, electric/magnetic fields, light, mechanic probes) and environments (e.g., liquids, gases) most successfully in TEM with high precision and controllability. On the other hand, SEMs with their large space available, stronger interaction at lowered electron energies and steady improvements in resolution promise high potential for dynamic studies as well. When coupled to efficient detection with novel experimental designs or new detectors, unprecedented details of dynamic processes in materials can be studied using imaging, diffraction and spectroscopy techniques. When tackling problems in beam sensitive materials, smart dose budgets, or correlative, complementary techniques using other probes have to be applied. In this symposium, we aim to highlight novel approaches to in situ and in operando microscopy, illustrated with applications in materials science. We welcome contributions on instrumental developments or novel use of existing equipment that can provide new insights into the dynamics of materials, including (but not limited to) nucleation and growth, phase transformations, surface and catalytic processes, functional properties, dynamics of defects, and degradation processes.

PST.7: Fast and Ultrafast Dynamics using Transmission Electron Microscopy

This session will focus on advances in the study of fast and ultrafast chemical and materials dynamics (structural, electronic, magnetic) with transmission electron microscopy instrumentation and methods. Abstracts are encouraged in (but not limited to) the following areas:

  • Techniques and instrumentation for high frame rate imaging and the science they enable.
  • Method and instrument development for increasing spatial, temporal, and energy resolutions in ultrafast transmission electron microscopes (UTEMs), both in stroboscopic and single-shot modes.
  • Pulse compression methods and schemes, including those for generating attosecond electron packets in the stroboscopic mode and sub-nanosecond packets in the single shot mode.
  • Laser technology/architecture and other means for generating discrete electron packets (e.g., RF cavities) that expand UTEM capabilities and the application space.
  • UTEM-compatible cathode developments; including those based on swept beams, field emission, Schottky-type, and thermionic electron guns.
  • Discoveries, new physical insights, and paradigm tests that have occurred because of, and have been enabled by, UTEM developments and advancements.

In addition to communicating technology developments and the new scientific advances resulting from UTEM experiments, a goal of this symposium is to stimulate discussions on future directions of fast and ultrafast TEM and to foster the formation of new collaborations and new ideas within the community.
