Abstract
A 10-band k.p model has been adopted to study the electronic transport properties of dilute III–V-nitride alloys. The N incorporation into III–V material causes a significant band gap reduction. The shapes of electrons effective mass is investigated as a function of N concentration. The mobility of electron \({{\mu }_{e}}\) in GaNxAs1 – x, InNxP1 –x, InNxAs1 –x and InNxSb1 –x shows a significant decrease for nitrogen composition less than 1%. In the range 1–5% observed in InNxP1 –x, InNxAs1 –x and InNxSb1 –x, however, there is a slow increase. In contrast the modification of electrons mobility affects profoundly the electron conductivity. The variation of electron conductivity as function of N composition is shown as well.
