Event Summary

We invite you to join us for our EM User Group meeting with a focus on Materials Research and Electronics. The objective of this meeting is to support knowledge exchange between researchers and to expand our understanding of materials and electronic components.

The meeting agenda consists of talks from researchers in the community and expert users from ZEISS, with a focus on application talks. The talks will be split into two focus streams; Materials Research and Electronics. Each stream will focus on key topics specific to that field. There will also be live remote demonstrations of selected ZEISS electron microscopes and a tour of the Hercules facility (University of Leicester).

Hercules is an EPSRC funded facility for correlative analysis of crystals in 3D. The project aims to provide an open, easy to access facility for users both in Leicester and across the UK. This newly founded facility is host to cutting-edge technology, including a Crossbeam 350 FIB-SEM with femtosecond laser ablation and an Xradia Crystal CT microCT with diffraction contrast tomography capability.

Join us for two days of knowledge sharing and networking opportunities. Registration closes February 12, 2024.

Live Virtual Demos

We are pleased to demo three of our most versatile electron microscopes and to give you the opportunity to ask our specialists your questions during these interactive sessions. Read on to learn more about what to expect during the live demo sessions.

  • ZEISS GeminiSEM 560
    High resolution image of montmorillonite particles obtained at 800 V beam energy. Even though the sample is non-conductive, fine flakes on the fractured surface can be well resolved.

    ZEISS GeminiSEM 560

    During the "GeminiSEM 560 for Ultra Low kV Imaging" demo, you will see high performance even under low kV conditions on challenging, non-conductive samples. You will also see that ease-of-use was principle in the design of this instrument and this will help you to obtain research-grade images on even the most challenging specimens.

    The GeminiSEM 560 is the pinnacle of field emission scanning electron microscopy (FESEM) at ZEISS. It is the ultimate high-resolution low-kV FESEM, featuring best resolution of 0.8 nm at 1 kV - achieved without the need for sample bias or source monochromation.

    The GeminiSEM 560 features the Gemini III electron column, the latest evolution of our tried and tested Gemini electron column. As with the Gemini I column, which celebrated its 30th anniversary in 2023, the Gemini III column features beam booster and electrostatic final lens. This is already designed for low kV performance. The Gemini III column also includes a nanotwin lens to provide the additional boost in performance. This lens even results in lower emission of magnetic fields than the Gemini I column.

  • ZEISS Crossbeam Laser
     These images (five in total) illustrate the preparation of an atom probe tomography (APT) sample using ZEISS Crossbeam laser. The sample is silicon. A specific site of the sample was marked by an ion beam induced deposition and prepared. First, a pillar is isolated from the bulk by laser machining. Next, the sample is shaped by FIB milling in steps.

Next, the sample is shaped by FIB milling in steps.

    ZEISS Crossbeam Laser

    During the "XRM to Crossbeam Laser Workflow" demonstration, you will see how the Crossbeam Laser can correlate with the data from the Xradia Versa, using it to target a specific region buried deep below the sample surface. The femtosecond laser works quickly to remove the bulk material whilst maintaining a surface finish suitable for EBSD mapping.

    The ZEISS Crossbeam combines imaging and analytical performance of a high resolution field emission scanning electron microscope (FE-SEM) with the processing ability of a next-generation Ga+ focused ion beam (FIB). Users can take advantage of ZEISS Crossbeam’s modular platform concept and high number of accessory ports to upgrade your system for any growing needs, e.g. with the LaserFIB for massive material ablation.

    The femtosecond laser ablation module allows rapid access of deeply buried regions of interest, execution of correlated workflows across multiple length scales and acquisition of better sample representativity with large-volume analysis. The rapid preparation capability allows for faster 3D imaging (including analytics) workflows and the improved surface finish means reduced or no additional milling to achieve desired imaging in some cases.

  • ZEISS Xradia 630 Versa

    ZEISS Xradia Versa 3D X-ray Microscope

    During the "XRM to Crossbeam Laser Workflow" demonstration, you will see how the Xradia Versa produces high resolution 3D datasets. The data will be used to identify a region of interested that is buried below the sample surface. This data can be correlated with the Crossbeam Laser, which can expose the region and perform the desired subsequent analysis.

    Extremely versatile ZEISS Xradia Versa 3D X-ray microscopes (XRM) provide superior 3D image quality and data for a wide range of materials and working environments. Xradia Versa XRM features dual-stage magnification based on synchrotron-caliber optics and revolutionary RaaD™ (Resolution at a Distance) technology for high resolution even at large working distances, a vast improvement over traditional micro-computed tomography. Non-destructive imaging preserves and extends the use of your valuable sample, enabling 4D and in situ studies.
