Comment on "Extreme lowering of the Debye temperature of Sn nanoclusters embedded in thermally grown SiO2 by low-lying vibrational surface modes"
Daniel B. Murray, Avra S. Laarakker, Lucien Saviot
Abstract
This Comment corrects two separate errors which previously appeared in the calculation of vibrational mode frequencies of tin spheres embedded in a silica matrix. The first error has to do with the vibrational frequency of a free elastic sphere. The second error has to do with the effect on the vibrational frequencies of a sphere due to its embedding in an infinite elastic matrix.
