Here, we present a materials study of InP membranes with embedded InGaAs multi-quantum wells (MQWs) directly grown above the Si waveguide layer via a tunnel epitaxy process. Cross-sectional scanning transmission electron microscopy, combining differential phase contrast imaging, energy-dispersive x-ray spectroscopy (EDX), and atomic-column-based strain analysis, confirms high-quality laterally grown InP membranes with defects confined to the V-groove region and elucidates facet-dependent MQW formation on (111)A, (110), and (111)B facets. Both EDX and strain analysis consistently reveal high-In, highly compressively strained (110) QWs (&gt;80% In), and no misfit dislocations are observed at InP\/InGaAs interfaces. In addition, under identical precursor ratios, ultra-thin QWs incorporate a higher indium composition than a thick bulk InGaAs region. These results provide practical guidance for designing efficient active regions in future electrically injected, Si-waveguide-coupled InP membrane lasers on SOI.<\/jats:p>","DOI":"10.1088\/1361-6528\/ae4985","type":"journal-article","created":{"date-parts":[[2026,2,24]],"date-time":"2026-02-24T22:48:03Z","timestamp":1771973283000},"page":"095201","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Integration of InP membranes with embedded InGaAs quantum wells on silicon-on-insulator by tunnel epitaxy"],"prefix":"10.1088","volume":"37","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5543-6969","authenticated-orcid":true,"given":"Zhao","family":"Yan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tim","family":"Grieb","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1086-5775","authenticated-orcid":true,"given":"Weiwei","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8811-1335","authenticated-orcid":true,"given":"Martin","family":"Ebert","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Florian F","family":"Krause","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Graham T","family":"Reed","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David J","family":"Thomson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andreas","family":"Rosenauer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6875-7403","authenticated-orcid":true,"given":"Qiang","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"266","published-online":{"date-parts":[[2026,3,4]]},"reference":[{"key":"nanoae4985bib1","doi-asserted-by":"publisher","DOI":"10.1063\/5.0050117","type":"journal-article","article-title":"Perspective on the future of silicon photonics and electronics","volume":"118","author":"Margalit","year":"2021","journal-title":"Appl.
