Their structural, optical and electrical properties have been studied.   X- ray studies of the films showed that the as-prepared films of Ag2S were             a mixture of both amorphous and polycrystalline phases, while Ag2S/ Ni films were found to be polycrystalline. Annealing of the films of Ag2S and Ag2S/ Ni at 200 ºC for   3 h led to further crystallization. The films contained a random distribution of small crystallites and at annealing temperature 200°C show the over-growth of particles on the smooth film surface. The optical band gap of the Ag2S thin films was evaluated from the analysis of the absorption spectra and estimated to be between  2.2 eV- 2.4 eV. Rise and decay of photoconductivity was studied at room temperature. The sheet resistance was 106 Ω/ square and electrical resistivity is of the order of 102-103 Ω cm, determined by Van der Pauw four- point probe method. Sheet carrier density, hall mobility can be determined from Hall Effect measurement. Variation of magnetoresistance and Hall voltage measurement was determined."}]},"item_1583103108160":{"attribute_name":"Keywords","attribute_value_mlt":[{"interim":"Thin Films"}]},"item_1583103120197":{"attribute_name":"Files","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2020-08-17"}],"displaytype":"preview","filename":"CHARACTERIZATION OF Ni Ag THIN FILMS.pdf","filesize":[{"value":"1.9 Mb"}],"format":"application/pdf","licensetype":"license_0","url":{"url":"https://meral.edu.mm/record/2977/files/CHARACTERIZATION OF Ni Ag THIN FILMS.pdf"},"version_id":"cd319670-c349-491b-a6b9-48b78bdb4918"}]},"item_1583103233624":{"attribute_name":"Thesis/dissertations","attribute_value_mlt":[{"subitem_awarding_university":"University of Yangon","subitem_supervisor(s)":[{"subitem_supervisor":"Pho Kaung"}]}]},"item_1583105942107":{"attribute_name":"Authors","attribute_value_mlt":[{"subitem_authors":[{"subitem_authors_fullname":"Myo Mon Mon Wynn"}]}]},"item_1583108359239":{"attribute_name":"Upload type","attribute_value_mlt":[{"interim":"Publication"}]},"item_1583108428133":{"attribute_name":"Publication type","attribute_value_mlt":[{"interim":"Dissertation "}]},"item_1583159729339":{"attribute_name":"Publication date","attribute_value":"2011-05-10"},"item_title":"Characterization Ni/Ag Thin Films","item_type_id":"21","owner":"61","path":["1595850252716"],"publish_date":"2020-08-17","publish_status":"0","recid":"2977","relation_version_is_last":true,"title":["Characterization Ni/Ag Thin Films"],"weko_creator_id":"61","weko_shared_id":-1},"updated":"2021-12-13T01:21:16.344301+00:00"}
