The spectrum of emitted electrons from GLS has been obtained by retarding potential method. The state of the surface has been evaluated using scanning electron microscopy (SEM) and field emission microscopy (FEM). The peculiarities of the structure of experimental samples were analyzed by the methods of Raman spectroscopy and X-ray diffraction. It has been found that the maximum of the energy distribution is displaced 6.1–6.8 eV below the vacuum values. It has been observed that with the growth of the electric field the maximum of the energy distribution shifts to the region of low energies while the energy spectrum broadens up to 0.7–1.2 eV. Studies of the emitting surface by FEM and SEM allowed one to conclude that the surface is sufficiently smooth. The field enhancement factor due to the micro-roughness does not exceed 3–10 times.","PeriodicalId":328869,"journal":{"name":"2016 14th International Baltic Conference on Atomic Layer Deposition (BALD)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122021918","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}

Only ten years later devices transform to vacuum and stainless steel chambers with ingenuous automation. In the beginning of 70-s ML-ALD technology had no role to play in electronics neither in SU not in other countries as the gate insulator has hundreds of angstroms.

In Leningrad science school flow type (travelling wave) reactors were in use till the mid of 90-s. Besides oxide materials in our laboratories II–VI compounds were synthesized. The chamber of rotation type with substrate laid on hot plate and two zones of precursors divided by quartz plates from inert purge gas zones. In the middle of 90-s we decided an issue by inverting substrate and made levitation type of a chamber.

This study presents numerical tools for quantitative interpretation of the EPES signal. They include modules for peak detecting, estimating the elastic peak intensities and retrieving composition-versus-depth profiles. The latter is based on the transport theory and invokes the straight line approximation (SLA). The examples of profile retrieval using the SLA are given.
