Influence of N defects on dielectric properties of Diamond
Abstract (englisch):
Atomistic structures and elastic and dielectric properties including first
simulations of loss tangent, tan 𝛿 of diamond with small nitrogen impurities
can be calculated using the first principles methods. The effect
of a single nitrogen substitutional atom on the Raman and IR absorbance
spectra is analyzed and compared with other calculations.
It is shown that nitrogen defects do not affect tan 𝛿 at far IR region
used in diamond windows in fusion reactors for plasma heating and
stabilization.
