By optimizing nucleation and growth on Si(111) substrates AlN layers are obtained with twist and tilt values comparable to MOVPE grown samples and with very low surface roughness free of any columnar structure. Also the entire compositional range of AlGaN has been addressed by co-sputtering of Al and Ga.

The SL structure was analyzed by the ω-2θ results around the InP (004) symmetric plane measured by high-resolution X-ray diffraction. In order to estimate a thickness of intermixing layers, we alternatively proposed a model using Fourier transform of a periodic trapezoid-shape scattering function to fit to an intensity of high-order satellite peaks. Our results show that purging the InGaAs terminated surface with TBP for 2–4 s could effectively remove residual As atoms and reduce As carry-over in the next-grown InP layer. By purging the InP terminated surface with TBA, even though an effect of P carry-over is reduced, the SL becomes more suffered from a diffusion of As atoms into the beneath InP layer.","PeriodicalId":382443,"journal":{"name":"2022 Compound Semiconductor Week (CSW)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122397747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
