High spatial resolution energy dispersive X-ray spectrometry in the SEM and the detection of light elements including lithium
Current technology for energy-dispersive X-ray spectrometry using silicon-drift detectors in combination with the latest field-emission scanning electron microscopes delivers routine nanoscale characterisation of structures as small as 50 nm. This performance relies on a combination of high spectral resolution and large sensor area. Results from the latest developments in low-noise electronics and windowless detectors show the possibility of analysing structures down to 10 nm and the sensitive detection of light elements, including, for the first time, lithium.
