532 nm Raman spectra of ; (a) Nonnormalized spectra of synthesized under increasing microwave power showing decreasing PL background and (b) Fitted spectrum of an (400 W) showing contributions from and modes, , and modes, and PPV 1175 and modes. An asymmetric peak at is the second order Si.
Variation in (a) ratio, (b) peak position (per centimeter), (c) FWHM for peak, and (d) the total relative intensity for PPV contributions, as a function of changing ionization power.
Variation in (a) hydrogen content, (b) -phase amount, (c) band gap, and (d) mass-density as a function of microwave plasma power. Data points were fitted with an independent variable Lorentzian line shape.
Variation in (a) and (b) optical constants for as a function of microwave ionization power.
