Abstract
(EN)
A tetrahedral amorphous carbon (ta-C) thin film (1A) is obtained by laminating a first unit structure (11) and a second unit structure (12) in this order on a base (10). In the first unit structure (11), a first layer (11a) and a second layer (11b) have sp3 bond fractions different from each other, and the second layer (11b) and a third layer (11c) have sp3 bond fractions different from each other. In the second unit structure (12), a first layer (12a) and a second layer (12b) have sp3 bond fractions different from each other, and the second layer (12b) and a third layer (12c) have sp3 bond fractions different from each other.

Cette invention concerne un film mince (1A) en carbone amorphe tétraédrique (ta-C) obtenu par stratification d'une première structure monobloc (11) et d'une seconde structure monobloc (12) dans cet ordre sur une base (10). Dans la première structure monobloc (11), une première couche (11a) et une deuxième couche (11b) ont des fractions de liaisons sp3 différentes les unes des autres, et la deuxième couche (11b) et une troisième couche (11c) ont des fractions de liaisons sp3 différentes les unes des autres. Dans la seconde structure monobloc (12), une première couche (12a) et une deuxième couche (12b) ont des fractions de liaisons sp3 différentes les unes des autres, et la deuxième couche (12b) et une troisième couche (12c) ont des fractions de liaisons sp3 différentes les unes des autres.
(JA)
ta-C薄膜(1A)は、基材(10)上に、第1の単位構造(11)及び第2の単位構造(12)がこの順に積層されてなる。前記第1の単位構造(11)は、第1層(11a)及び第2層(11b)でsp結合の含有量が互いに異なり、第2層(11b)及び第3層(11c)でsp結合の含有量が互いに異なる。前記第2の単位構造(12)は、第1層(12a)及び第2層(12b)でsp結合の含有量が互いに異なり、第2層(12b)及び第3層(12c)でsp結合の含有量が互いに異なる。
