(Color online) SEM images of Zn3N2 samples grown at (a) 298 and (b) 473 K. Inset: linear scan obtained with the stylus profilometer.
(Color online) (a) Ψ and (b) Δ of layers grown at different Ts vs. photon energy. Lines represent the fitting curves of the three-phase model.
(Color online) Experimental data of Zn3N2 layer grown at 298 K with 1 week in ambient, and fitting curves of the three-phase model.
(Color online) Film grown at 298 K after 1 week in air exposure. The inset points out the stoichiometry changes near the surface.
(Color online) Optical constants of Zn3N2 film grown at 373 K as a function of the photon energy.
(Color online) Squares: reflectance measured in a film grown at 373 K; line: reflectance calculated from the n and k values.
