Lithium Diffusion Tester

UHV System to Characterize Lithium Concentrations & Surface Crystallographic Changes

Model LDT200

Lithium Diffusion Tester, Model LDT200 is a complete ultra-high vacuum system to characterize the lithium concentration on the surface of tested material and surface crystallographic changes on single-crystal substrates. It has the capability to measure the Lithium diffusion rate and diffusion activation energy using variable temperature sample stage from cryogenic temperatures to 1000 C. This method is based on creating a concentration gradient of Lithium on the surface by evaporation of Lithium on tested material in an ultra-high vacuum environment and tracing Lithium concentration using Auger electron spectroscopy (AES). The structural effect of lithium deposition and diffusion on the host materials is measured on the surface using Low Energy Electron Diffraction (LEED). The capacity of tested material for Lithium storage can be also measured using this method.
