Abstract

Molybdenum nitride films γ- Mo 2 N/Si have been fabricated with reactive magnetron sputtering in ( N 2 + Ar ) gas mixture. Phase composition of the films has been defined with reflection high energy electron diffraction. Refractive index and extinction coefficient of γ- Mo 2 N have been evaluated with laser ellipsometry at λ = 632.8 and 488.0 nm. Upper limit of γ- Mo 2 N film thickness measurable with laser ellipsometry has been found to be ~80 nm.
