“…been reported for W(110), Mo(110), Ta(110) [Bet74], Re(10-10), Re(0001), Ro(111), Ir(111) [Bet68], Pb(111) [Deg06a], Cu(111) [Gie01], and Au(100) [Hir01] structures, while step bunch formation and collapse was noticed e.g. for W(110) and Mo(110) emitters in the presence of carbon or silicon [Bet74]. It is known that adsorbates can induce step bunch formation [Hor98] and considering the height of islands on the facet in a collapse process (Fig.…”

“…14͒ structures, while step-bunch formation and collapse were noticed, e.g., for W͑110͒ and Mo͑110͒ emitters in the presence of carbon or silicon. 11 It is known that adsorbates can induce step-bunch formation, 15 and considering the height of islands on the facet in a collapse process ͑Fig. 3͒, this also seems to be the case for the Schottky emitter, which has the ZrO x adsorbates on the W͑100͒ terraces.…”

“…[Backscattering energy spectrum of 2 MeV 7 Li' ions for an Al target with adsorbed Pd (detection angle : 03B8lab = 160° , resolution : 1.8 kev/canal) . Compte tenu des relations (11) et (13), le maximum de travail de sortie moyen est obtenu pour une concentration moyenne sur la pointe : 03A6max = (0,60 + 0,06) 1015 atomes PdJcm2 .…”

“…La pointe est portée à 1 200 K pour répartir le dépôt sur l'ensemble de sa surface. L'observation, à la température ambiante, du diagramme d'émission de champ révèle l'existence [10, 11,12] de facettes {334} à partir d'une concentration superficielle moyenne de carbone caractéristique et reproductible que nous avons adoptée comme dose unitaire.…”
