Abstract :
Optical secondary emission (SE) spectra of as-grown and annealed in 5 × 10−6 Torr vacuum at 900, 1100 and 1150°C during 30 min free standing CVD-diamond films under microbeam of 515 and 488 nm laser radiation excitation were investigated. Several ultranarrow lines and fine structured with 5–8 meV energy interval Gauss-like maxima and stepped band were resolved. Dependences of SE spectra components on pumping power and heat-treatment conditions were investigated. Qualitative discussions of spectroscopy data on the base of electronic inelastic scattering were presented.
