(004) HRXRD spectra of the four GaNAs(Sb) layers. (a) , (b) , (c) , and (d) . The tensile strain decreases with increasing Sb flux.
(004) HRXRD spectrum of the sample with its corresponding simulated spectrum.
(224) reciprocal space map of the GaNAsSb sample with BEP Sb.
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.
The valence-band splitting vs the strain in the GaNAs(Sb) layer.
PL spectra of the GaNAs(Sb) samples showing a redshift and increase in intensity with increasing antimony flux. (a) , (b) , (c) , and (d) .
Summary of GaNAs(Sb) compositions obtained from SIMS, antimony flux used, and strain determined from HRXRD.
