Absorption and Raman scattering processes in InN films and dots

O Briot, B Maleyre, S Ruffenach, B Gil, C Pinquier… - Journal of crystal …, 2004 - Elsevier
We demonstrate that the phonon frequencies that are reported in the literature for indium
nitride (InN), films are all consistently correlated to the strain state of the material. Raman …

Absorption and photoluminescence features caused by defects in InN

D Alexandrov, KSA Butcher… - Journal of crystal …, 2004 - Elsevier
Linear combination of atomic orbitals electron band structure calculations are used to
examine the influence of common defect structures that may arise as artifacts during the …

Detailed analysis of absorption data for indium nitride

KSA Butcher, M Wintrebert-Fouquet, PPT Chen… - Materials Science in …, 2003 - Elsevier
It is shown that the 0.7 eV band gap recently announced for InN is actually due to a sub
band gap deep level trap with| s〉 like symmetry. This level had been known in the literature …

The value of the direct bandgap of InN: a re‐examination
