Phonon spectrum and vibrational characteristics of linear nanostructures in solid matrices
E. V. Manzhelii, S. B. Feodosyev, I. A. Gospodarev +2
The atomic dynamics of linear chains embedded in a crystalline matrix or adsorbed on its surface is studied. A linear chain formed by substitutional impurities in a surface layer a…

Low temperature anomaly of heat capacity of CD4 rotors in solid CD4-Kr solution
M. I. Bagatskii, V. V. Dudkin, V. G. Manzhelii +2
The heat capacity of the solid Kr-CD4 (13% CD4) solution has been investigated. It is shown that the temperature dependence of the heat capacity Crot of the rotational subsystem in…
