Magnetoresistance of nanocomposite copper/carbon thin films

Structure and Optical Characteristics of DLC Films

“…This phenomenon can be attributed to the hybridization state of carbon atoms, whereby a reduction in sp 2 bonding in the films leads to an expansion of the optical bandgap. This is because the carbon-carbon sp 2 states are positioned between the carbon-carbon sp 3 states, resulting in a blue shift of the optical bandedge [23]. Notably, similar trends have been observed by Angus [24] and Dischler et al [25], who found that reducing the hydrogen content in carbon films led to a decrease in the optical bandgap.…”

“…There has been increasing interest in diamond-like carbon (DLC) thin films in recent years due to their exceptional properties, which make them suitable for various industrial applications. Such characteristics consist of electrical, magnetoresistance, mechanical propertice, and resistance to chemical corrosion [1][2][3][4][5]. As a result, DLC films have become an essential component in various industries, particularly in the production of optical coatings and wear-resistant coatings for computer hard disks that can effectively transmit both infrared and visible light.…”

“…Additionally, significant amounts of hydrogen, further expanding their diversity, are offen introduced into nanocrystalline and amorphous carbon films which can be found in various diversity. The most prevalent chemical bonds in these materials are sp 3 and sp 2 hybridizations. In the sp 3 arrangement, a carbon atom forms four sp 3 orbitals, creating a robust bond with its neighboring atoms.…”

“…The most prevalent chemical bonds in these materials are sp 3 and sp 2 hybridizations. In the sp 3 arrangement, a carbon atom forms four sp 3 orbitals, creating a robust bond with its neighboring atoms. Notably, some DLC films exhibit exceptionally high hardness, with an sp 3 content exceeding 80% [6][7][8].…”

Quantitative Investigations about the Surface Texture Characteristics of the Nickel-Carbon Composite Thin Films using Stereometric Analysis

“…Carbon nanocomposites containing metal nanoparticles in the carbon amorphous environment have attracted the attention of researchers owing to their interesting physical applications to investigate their application in various industrial and medical fields [4][5][6], and they can also be used as coating materials in electronics, spintronics, optics, biomedicine, and ferroelectric memories [7][8][9].…”
