Am. Mintairov et Dm. Mazyrenko, PLASMON-PHONON MODES AND CLUSTERING EFFECTS IN RAMAN-SPECTRA OF N-INXGA1-XAS, International journal of electronics, 77(3), 1994, pp. 309-316
Theoretical and experimental investigations on Raman scattering spectr
a of optical phonons and plasmon-phonon modes of undoped and Si-doped
InxGa1-xAs (n almost-equal-to 10(15)-10(19), x = 0.05-0.3) are present
ed. It is shown that optical phonons of InxGa1-xAs for x = 0.1-0.3 hav
e three mode behaviour and an additional band in the Raman spectra of
this ternary alloy is associated with clusters having (GaAs)1(InAs)1 s
uperlattice structure. The parameters of optical phonons and plasmons
of n-InxGa1-xAs are measured.
