英文摘要We have investigated the optical transitions in ga1-yinynxas1-x/gaas single and multiple quantum wells using photovoltaic measurements at room temperature. from a theoretical fit to the experimental data, the conduction band offset q(c), electron effective mass m(e)*, and band gap energy e-g were estimated. it was found that the q(c) is dependent on the indium concentration, but independent on the nitrogen concentration over the range x=(0-1)%. the m(e)* of gainnas is much greater than that of ingaas with the same concentration of indium, and increases as the nitrogen concentration increases up to 1%. our experimental results for the m(e)* and e-g of gainnas are quantitatively explained by the two-band model based on the strong interaction of the conduction band minimum with the localized n states.
