Webinar: Correlative STEM-CL and EDS for photovoltaic and optoelectronic devices

Titled “Correlative Analytical Workflow with STEM-CL and EDS for Photovoltaic and Optoelectronic Devices,” the webinar will explore how Cathodoluminescence (CL) spectroscopy in Scanning Transmission Electron Microscopy (STEM) can provide nanoscale maps of band gaps and defect-related sub-band-gap states—offering valuable insight into the optoelectronic properties of advanced devices.

Using examples from CdTe photovoltaic thin films and InGaN-on-Si LEDs, the speakers will demonstrate how correlative STEM-CL can be used to investigate the relationship between composition, defects and local optoelectronic properties. The session will also cover practical considerations for STEM-CL analysis, including FIB sample preparation, specimen thickness and cryogenic measurements.

A key highlight of the workflow is the use of an Attolight Mönch CL detector integrated on a Thermo Scientific Talos F200i STEM, demonstrating the capabilities of high-resolution cathodoluminescence for advanced correlative materials characterisation.

Join the webinar to discover how combining optical, structural and chemical information at the nanoscale can provide deeper insights into the materials that underpin tomorrow's photovoltaic and optoelectronic technologies.

📅 13 October 2026 | 3:00–4:00 PM BST
👥 Speakers: Dr Stuart Robertson and Dr Zhaoxia Zhou, Loughborough Materials Characterisation Centre (LMCC), Loughborough University, together with experts from Thermo Fisher Scientific.
