Graphene is a crystalline form of carbon defined as a hexagonal arrangement of carbon atoms in a one-atom thick planar sheet. Graphene has outstanding properties (mainly mechanical strength, optical transparency and excellent electrical and heat conductivity) that make it an attractive material for electronics applications. Traditionally, graphene structures have been imaged with aberration-corrected TEM, AFM, or STM.

Real-time observation and analysis during the charge-discharge cycle can provide critical insights into the chemical and structural changes that occur within these solid-state battery systems. JEOL offers unique opportunities for this type of study from sample preparation to in-situ observation, all under an air-isolated workflow to protect components that are reactive to air.

This study demonstrates that in-situ tensile testing combined with SEM imaging and EBSD mapping enables continuous observation of crystal orientation changes at the microscale.

The combination of Scanning electron microscope (SEM) imaging and embedded microanalysis (EDS) offers the perfect combination of direct particle visualization and chemical information at the same time. The recent emergence of automated solutions and multi area analyses has brought this technique to the forefront of the available automated particle analysis solutions.

For people who are using the SEM for the first time. Includes topics such as What is the SEM, Observation  Examples, Specimen Preparation and Observation Technique, Functions of SEM's Individual Components, New Functions of SEM, Comparison of Scanning Electron Microscope with Optical Microscope and Transmission Electron Microscope, and Description of Terms.

SEM is a natural extension to viewing specimens with an optical microscope due in part to its inherent higher depth of field and ability to resolve smaller microstructures. Creating a 3-dimensional (3D) surface model can further enhance our understanding with specimens that have complex topographical features.

JEOL SEMs are delivered with the capability for remote viewing and remote operation. The SEM computer includes a 2nd ethernet card for connection to your local area network. There is no need for a second support computer. Just connect your JEOL SEM computer to a reliable and fast broadband internet connection and choose the software platform that meets your remote access requirements.
