△ [15p-A21-4] Composition pulling effect near lattice-matching condition in InGaN films grown on ScAlMgO4(0001) substrates
Keywords:Nitride semiconductors, InGaN, ScAlMgO4
One of the main issues on InGaN-based light emitters is large lattice mismatch between InGaN and GaN in the longer wavelength region. ScAlMgO4(SCAM) is a candidate substrate to solve it because it can realize the lattice matching with In0.17Ga0.83N. In-rich InGaN grown on strain-free In0.17Ga0.83N/SCAM templates have smaller lattice mismatch than conventional device structures. In our study, the composition pulling effect in InGaN/SCAM films is demonstrated.
