Web24 sep. 2024 · The solid-state, lithium-drifted silicon detector [Si(Li)] was developed and applied to x-ray detection in the 1960s. By the early 1970s, this detector was firmly established in the field of x-ray spectrometry and was applied as an x-ray detection system for SEM and x-ray spectrometry. The Si(Li) detector provides excellent resolution.
