Design of thin DLC/TiO2 film interference coatings on glass screen protector using a neon–argon-based gas injection magnetron sputtering technique

The Amorphous Carbon Thin Films Synthesized by Gas Injection Magnetron Sputtering Technique in Various Gas Atmospheres

“…The result is an increase in the population of carbon ions. In the last few years, the literature reports using an alternative for Ar gases to increase the ionization degree of magnetron plasma [55][56][57][58][59].…”

Optical Properties of Amorphous Carbon Thin Films Fabricated Using a High-Energy-Impulse Magnetron-Sputtering Technique

“…Moreover, if the amount of sp 3 bonds is greater than 80%, the tetrahedral carbon (ta-C) can be distinguished [3][4][5][6][7][8]. Properties of a-C strongly depend on the ratio of sp 2 /sp 3 ; therefore, the method of fabrication and growing conditions play crucial roles during the synthesis of a-C materials [1,3,4,[9][10][11][12][13][14][15][16][17][18][19][20].…”

“…The layers are produced by various methods, mainly physical or chemical vapor deposition methods. In the last few decades, many publications on their production and describing their properties have been published, and the interest in new/modified methods of their synthesis still continues [3,[10][11][12][13][16][17][18][19]. The common factor linking these works is the connection of the composition of the layers (usually the sp 2 /sp 3 ratio-the dominant factor) with the fabrication conditions of these materials.…”

“…The common factor linking these works is the connection of the composition of the layers (usually the sp 2 /sp 3 ratio-the dominant factor) with the fabrication conditions of these materials. The analysis of the literature shows that there are three main factors determining the optoelectronic properties of carbon layers [3,10], i.e., the ratio of the number of sp 2 /sp 3 bonds [12,13,[16][17][18][19], the sp 2 cluster size, and the distribution of sp 2 clusters in the sp 3 matrix [10,11].…”

“…The amorphous carbon films with a high content of sp 3 bonds exhibit a high mechanical hardness, wear and corrosion resistance, low friction, good optical transparency, a wide band-gap, and chemical inertness [3,[21][22][23]. Because of their excellent properties, these coatings are considered in a range of applications: anticorrosive [3], biomedical [24,25], optical [18,26,27], antiwear [28,29], etc. Therefore, the efficient methods enabling the synthesis of carbon films are still developed, and such modifications of them are sought which can lead to the fabrication of coatings with a high sp 3 content.…”
