“…Among the nanostructures grown on GaP substrates and/or GaP/Si pseudo substrates, dilute nitride quantum wells (QW) (GaAsPN and InGaPN) appear among the most reported in the literature. [5][6][7] Nevertheless, further optimization is still required to decrease the threshold current densities in the laser devices based on such nanostructures (4 kA.cm À2 in pulsed mode at 300 K on GaP substrate 8 and 4.4 kA.cm À2 in pulsed mode at 120 K on Si substrate 9 ). Quantum dot (QD) based active zones offer a reliable alternative to QW-based laser structures, as it may take advantage of the lower dimensionality to reduce the threshold current densities.…”

“…Значения ширины запрещенной зоны для GaP 0.893 N 0.037 As 0.07 и GaP 0.98 N 0.02 составляли 1.78 эВ [6] и 2.0 эВ [3,13] соответственно. Эффективная масса элек-тронов для GaPNAs равнялась аналогичному значению для GaPN и составляла 0.9m e [14], где m e -масса электрона.…”

“…В соответствии с экспериментальными данными, пред-ставленными в работах [5,15], значение подвижностей электронов и дырок составляло 50 см 2 В −1 с −1 . Значения разрыва зон проводимости на гетерограницах GaP/GaPN и GaP/GaPNAs составляли 0.27 эВ [13] и 0.5 эВ [16] соответственно. Значение разрыва валентных зон на гетерогранице GaP/GaPN составляло 0.03 эВ [13], при этом значения энергии сродства к электрону для GaP, GaPN и GaPNAs составляли 3.8, 4.07 и 4.3 эВ соответ-ственно.…”

“…The band alignment was evaluated by a calculation method accounting for the band-anticrossing (BAC) model [27] and the model-solid theory [28]. This calculation method is able to describe the band alignments in compressively strained InGaPN/GaPN SQWs on GaP and Si [29]. In this calculation, we did not include the thin 4-ML-thick GaP capping layer.…”
