Materials and processes
The Nanocharacterization platform’s (PFNC) partner labs are committed to regular equipment upgrades to ensure that the facility remains at the international state of the art. This year, the platform’s transmission electron microscopes (TEM) were upgraded with some new capabilities.The Titan Themis TEM was outfitted with two spectrometers, which, when used together, can provide additional information on the chemical makeup of the materials analyzed. They can also give researchers insights into materials’ chemical bonds and optoelectronic properties with atomic-scale resolution. The Titan Ultimate TEM, which holds the world record for spatial resolution at 50 picometers, got its own ultra-fast CMOS camera. “When the camera is used with an instrumented sample holder, it can be used for both in situ and in operando observations,” said one researcher. “This is useful for observing dynamic phenomena like atom movements on 2D materials like graphene and phase-change materials like those used for memory.”The platform’s three partner institutes need these advanced observation capabilities for their work on batteries, fuel cells, photovoltaics, microelectronics, and power electronics, for example.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
