The influence of AlN interlayers on the microstructural and electrical properties of p-type AlGaN/GaN superlattices grown on GaN/sapphire templates
Abstract AlN with different thicknesses were grown as interlayers (ILs) between GaN and p-type $ Al_{0.15} $$ Ga_{0.85} $N/GaN superlattices (SLs) by metal organic vapor phase epitaxy (MOVPE). It was found that the edge-type threading dislocation density (TDD) increased gradually from the minimum of...

520 | |a Abstract AlN with different thicknesses were grown as interlayers (ILs) between GaN and p-type $ Al_{0.15} $$ Ga_{0.85} $N/GaN superlattices (SLs) by metal organic vapor phase epitaxy (MOVPE). It was found that the edge-type threading dislocation density (TDD) increased gradually from the minimum of 2.5×$ 10^{9} $ $ cm^{−2} $ without AlN IL to the maximum of 1×$ 10^{10} $ $ cm^{−2} $ at an AlN thickness of 20 nm, while the screw-type TDD remained almost unchanged due to the interface-related TD suppression and regeneration mechanism. We obtained that the edge-type dislocations acted as acceptors in p-type $ Al_{x} $$ Ga_{1−x} $N/GaN SLs, through the comparison of the edge-type TDD and hole concentration with different thicknesses of AlN IL. The Mg activation energy was significantly decreased from 153 to 70 meV with a 10-nm AlN IL, which was attributed to the strain modulation between AlGaN barrier and GaN well. The large activation efficiency, together with the TDs, led to the enhanced hole concentration. The variation trend of Hall mobility was also observed, which originated from the scattering at TDs. | ||

abstract |
Abstract AlN with different thicknesses were grown as interlayers (ILs) between GaN and p-type $ Al_{0.15} $$ Ga_{0.85} $N/GaN superlattices (SLs) by metal organic vapor phase epitaxy (MOVPE). It was found that the edge-type threading dislocation density (TDD) increased gradually from the minimum of 2.5×$ 10^{9} $ $ cm^{−2} $ without AlN IL to the maximum of 1×$ 10^{10} $ $ cm^{−2} $ at an AlN thickness of 20 nm, while the screw-type TDD remained almost unchanged due to the interface-related TD suppression and regeneration mechanism. We obtained that the edge-type dislocations acted as acceptors in p-type $ Al_{x} $$ Ga_{1−x} $N/GaN SLs, through the comparison of the edge-type TDD and hole concentration with different thicknesses of AlN IL. The Mg activation energy was significantly decreased from 153 to 70 meV with a 10-nm AlN IL, which was attributed to the strain modulation between AlGaN barrier and GaN well. The large activation efficiency, together with the TDs, led to the enhanced hole concentration. The variation trend of Hall mobility was also observed, which originated from the scattering at TDs. © Springer-Verlag 2012 |
