FIG. 1.

(004) HRXRD spectra of the four GaNAs(Sb) layers. (a) , (b) , (c) , and (d) . The tensile strain decreases with increasing Sb flux.

FIG. 3.

(224) reciprocal space map of the GaNAsSb sample with BEP Sb.

Image of FIG. 4.
FIG. 4.

ER spectra of GaNAs(Sb) layers measured at with simulated fits. Experimental data are plotted by the open and solid circles. The open circles were neglected during the fitting procedure. The solid lines represent the simulation. The dashed lines represent modulus of individual resonance associated with the LH- and HH-related transitions.
