Irrespective of the deposition method, an anneal is required to activate the passivation. In this work, the reaction kinetics of the annealing process for radiofrequency reactively-sputtered AlOx is investigated. The effectiveness of the activation anneal critically depend on the ambient gas. A gas mixture of N2 and H2 is found to be the best annealing ambient for sputtered Al2O3 films, leading to an effective surface recombination velocity Seff of ∼5 cm/s. The experiments indicate that the surface passivation anneal follows an activation energy EA close to 1.1 eV.","PeriodicalId":11423,"journal":{"name":"ECS Solid State Letters","volume":"54 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87620917","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}

The as-grown GePb alloy has good crystalline quality, as confirmed by transmission electron microscopy. No dislocation or Pb precipitation is found in the GePb layer. High-resolution Rutherford Backscattering Spectrometry (HRBS) characterization indicates that substitutional Pb content in the GePb alloy is 0.2 ± 0.1%. There is a substantial loss of Pb atoms after GePb formation according to the HRBS results.
