摘要

We present photoluminescence measurements under intense magnetic fields (B up to 30 T) in n-doped indium nitride samples with carrier concentration ranging from about 7.5 × 10~(17) cm~(-3) to 5 × 10~(18) cm~(-3). The observation of transitions involving several Landau levels permits to determine the carrier-reduced mass /x around the Γ point. Depending on the carrier concentration, we find μ ranging between 0.093m_0 and 0.107m_0 (m_0 is the electron mass in vacuum). This finding poses a lower limit to the electron effective mass, whose unexpectedly large value (m_e≥0.093m_0) indicates that the sources of n doping in InN perturb strongly the crystal conduction band near its minimum.
