Figure 4

PL spectra at 15 K of ternary CL samples as a function of the growth rate. (a) Spectra of samples containing a GaAsN CL grown at 1 and 2 ML s−1 (D1 and D2, respectively), together with that of a sample with the CL grown at 1 ML s−1 using a lower RF plasma source power (D3). (b) Spectra of samples containing a GaAsSb CL grown at 1 and 2 ML s−1 (E1 and E2, respectively), together with that of a sample with the CL grown at 1 ML s−1 using a lower Sb effusion cell temperature (E3).
