Radiative recombination efficiency in InN is lower than the other III nitride binary compounds (GaN, AlN). Particularly, photoluminescence (PL) intensity in p‐InN is weaker than that in n‐InN by three orders or more. We investigate the nonradiative recombination (NR) processes in InN with respect to carrier density, activation energy of NR processes, and carrier scattering rate of the inside bulk region estimated by infrared (IR) measurements, and show that NR centers of p‐InN originate from the same defect species as those of n‐type films. We also compare PL properties of N‐polar and In‐polar samples, and show that NR process is initiated by electron capture by deep levels of accepter nature.
