Numerical Modeling of Thermal Desorption Spectra of Hydrogen: A Review of Thermal Desorption Models

Numerical modeling of thermal desorption spectra of hydrogen, which is used for identifying the hydrogen state in metals, is reviewed. The previously proposed models are described in the historical perspective by categorizing them according to the rate-determining processes of hydrogen detrapping and diffusion in the thermal desorption spectra. The range of validity of each model is also described.
