For different samples with effective thickness 2–6 nm the emission threshold (macroscopic electric field) varied between 3.0 and $6.5 mathbf{V}/boldsymbol{mu} mathbf{m}$. Titanium films having similar parameters showed to be incapable of emission field magnitudes $sim 10 mathbf{V}/boldsymbol{mu} mathbf{m}$. Results of AFM and SEM studies allowed us to associate this difference with different morphology of the deposited films. Films of Mo were comprised by separated irregular islands with 5–10 nm height and lateral sizes of tens of nanometers. Films of Ti were also discontinuous but consisted of larger domains having distinctly dendritic structure. These new findings are in good agreement with the results of previous studies performed with carbon island films.","PeriodicalId":296618,"journal":{"name":"2018 IEEE International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114446971","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 simulations are performed for QPSK modulated subcarriers with different bandwidth compression factor values (0.5, 0.75 and 1) in the presence and absence of average power equalization. It is shown that SEFDM N-dimensional points have a few very close interfering points for medium compression factors. Thus, a special rule can be used to choose particular $N$-dimensional points to increase BER performance of SEFDM. The proposed results are useful for SEFDM coded modulation schemes development where non-informational subcarriers are chosen in the same way as in block error correction schemes.","PeriodicalId":296618,"journal":{"name":"2018 IEEE International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132305311","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}
