The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00005 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.07 SJR: 0.198 SNIP: 0.48 CiteScore™:: 1.1 H-Index: 20

ABSTRACT

The photovoltaic properties of silicon material are improved after a thermal and chemical treatment by inductive plasma Ar-H2. The diffusion length of minority carriers (LD) increases up to 200 mm despite a high dislocations concentration 106 cm-2 generated during the recrystallization of liquid silicon. The characterisation of different chemical phenomena responsible for such properties are determined by exodiffusion of hydrogen from solid silicon at high temperature and by analysis of the plasma excited species by emission spectroscopy. This study shows that the different states of atomic hydrogen produced in the electromagnetic field of the coil are responsible of the chemical properties of the plasma reacting with liquid silicon. The highly excited states of atomic hydrogen n=3 to n=8 of the Balmer series for hydrogen are identified by optical emission spectroscopy. The silicon dangling bonds react on dislocation with the hydrogen and are stable up to 1000 K.
