“…However, the BETO emission peak is strongly shifted towards low energies with a large broadening which corresponds to a decrease of the bandgap energy. This is consistent with a very high boron doping level [29] which is not surprising since the incorporation efficiency of dopants is known to be much higher on (111). Taking into account the boron doping measured by SIMS, an incorporation efficiency of almost 90% can be estimated which is almost 2 orders of magnitude higher than that obtained on (100) orientation in our growth conditions [30].…”

“…The impurity band model has been argued to be the appropriate explanation for cathodoluminescence spectra [61,62], whereas X-ray angle-resolved photoemission spectroscopy appears to reveal a Fermi-level lying below the host valence band top [63]. Much of the computational analysis appears to support the latter [51, 64 -68].…”

“…The reason for this is believed to be due to a band gap shrinkage. This shift can then be used to derive the B content 40. However, in this analysis a contribution of stress to the peak shift has to be taken into account, since stress alone shifts the exciton‐related peaks by ∼0.01 eV per GPa, as shown in Fig.…”
