Nanoindentation Young’s modulus of samples as a function of Be content. To avoid superposition, curves at 0.5 mN show the real value, those at 1 and 0.35 mN are shifted by and , respectively.

Representative TO (1) and LO (2) Be-Te Raman spectra corresponding to the Be content . TO modes are labeled with a subscript and a superscript that refer to the vibrating bond and to the host region (Be-rich or Zn-rich), respectively. LO modes couple via their long range polarization field giving rise to a giant mode that attracts most of the oscillator strength, leaving behind a residual mode at low frequency (Ref. 27). refers to the disorder-activated mode in the TO symmetry. The dependencies of the frequency of the lower TO mode and of the FWHM of the mode on the Be content are shown in the inset. Regarding a typical uncertainty is , as represented by the error bars. Most curves are guidelines for the eyes, except the curved line above 20% corresponding to a theoretical curve (Ref. 27).
