Thermodesorption of Argon Implanted in Germanium

Publications, 01 April 2020

We are glad to bring to your attention a new preprint «Thermodesorption of Argon Implanted in Germanium» P13-2019-60 published by the JINR Publishing Department. The authors of the work are Turek M. et al.


Thermal desorption spectroscopy (TDS) measurements of Ar implanted in germanium samples are reported. The Ar implantation energies were 100 and 150 keV while the fluence was 2 · 1016 cm−2. A sudden release of Ar at the temperatures 790-840 K was observed as sharp peaks of the thermodesorption spectrum. These peaks are probably related to the gas release from cavities in the germanium structure. Desorption activation energy of Ar was found using the Redhead analysis of the Ar peak shift. These values are much larger than the values obtained for thermodesorption of He implanted in germanium.

The investigation has been performed at the Dzhelepov Laboratory of Nuclear Problems, JINR, and at the Institute of Physics, M. Curie-Sklodowska University (Lublin, Poland).
