Summarizing, near-forward Raman scattering is used to study the bulk and surface PP’s of the three-mode [1(Zn-Se), 2(Be-Se)] Zn 0.67 Be 0.33 Se zincblende alloy, whose short

Applying the intuition based on tight binding to structures made out of rods, one may under- stand that sound can always propagate along the rods, therefore no localized

It has been observed for ferroelectric materials that ab initio phonon calculations give better agreement with experi- mental data if they are performed at the experimental

Suppose one studies the change in the bound state energy when one flips a spin nearest neighbour to the impurity in an otherwise completely

Experimental photoabsorption cross section for amorphous carbon in the vicinity of the K-edge compared with theoretical and compiled results. See text for details of

Two main collision processes will be studied in the present paper : acoustic phonons (deformation poten- tial), and polar optical phonons.. A general solution of these
