Findings on Physics Reported by Researchers at Monash University (Fast imaging with inelastically scattered electrons by off-axis chromatic confocal electron microscopy)

By a News Reporter-Staff News Editor at Physics Week -- Fresh data on Physics are presented in a new report. According to news reporting from Victoria, Australia, by VerticalNews journalists, research stated, "We introduce off-axis chromatic scanning confocal electron microscopy, a technique for fast mapping of inelastically scattered electrons in a scanning transmission electron microscope without a spectrometer. The off-axis confocal mode enables the inelastically scattered electrons to be chromatically dispersed both parallel and perpendicular to the optic axis."

The news correspondents obtained a quote from the research from Monash University, "This enables electrons with different energy losses to be separated and detected in the image plane, enabling efficient energy filtering in a confocal mode with an integrating detector. We describe the experimental configuration and demonstrate the method with nanoscale core-loss chemical mapping of silver (M4,5) in an aluminium-silver alloy and atomic scale imaging of the low intensity core-loss La (M4,5@840??eV) signal in LaB6. Scan rates up to 2 orders of magnitude faster than conventional methods were used, enabling a corresponding reduction in radiation dose and increase in the field of view."

According to the news reporters, the research concluded: "If coupled with the enhanced depth and lateral resolution of the incoherent confocal configuration, this offers an approach for nanoscale three-dimensional chemical mapping."
