Phonon modes in Pd-Pt and other substitutional alloys with large mass disorder
      
We study some aspects of the effect of mass disorder on the spectrum of the dynamical matrix of an infinite crystal in the harmonic approximation.
      
We also comment on the mathematical difference between the models treated and the system of phonons with mass disorder in the harmonic approximation, whose behavior is known to be of Debye form, not Lifschitz, at low temperatures.
      


The CPA method has been generalized to calculate the phonon structure of supe-rlattices consisting of alternately layered disordered alloy films.

本文推广应用CPA方法来计算由多层无序合金膜组成的超晶格的声子结构.仅考虑合金膜内的质量无序,而对力常数的无序采用虚晶(Virtual Crystal)近似,我们计算了无序超晶格的结构平均声子格林函数的自能及声子态密度曲线,并由此对无序引起该种材料振动模式的变化作了定性的分析.

We have investigated the phonon structure of the compositionally modulated alloysby the use of the CPA method, taking into account not only the mass disorder, butalso the force-constant disorder. The densities of the phonon states have been calculat-ed and compared with those in the case of the homogeneous alloys and in the case wi-thout considering the force-constant disorder.

不仅考虑质量无序,而且考虑到力常数的无序,本文用CPA方法研究了组分调制合金的声子结构.我们计算了声子态密度曲线,并与均匀合金的情况及不考虑力常数无序的情况作了比较.
