In DLN, two microstructures (hydrogenated carbon andoxygenated Silicon) are interpenetrating two each other and thus internalstress is decreased and adhesion property is increased and hence this compositehas improved adhesion to almost all kind of substrate. Ithas immense application in the filed of biomedical implants. This can be usedas biomedical sensors as well. DLC coatings can be used as protective wear resistantcoating in joint prostheses. 2 already deposited DLN coatings byPECVD method over various substrate like SS 316 L, glass, Si(100), ceramic(Al2O3)ultra high molecular weight polyethylene (UHMWPE), Co–Cr alloy, Ti6Al4V alloy,etc.
Most of these materials have been in use asload-bearing orthopedic implants, like hip joint, knee joint, etc 72. As its coefficient of friction is very less, DLNfilms can be used as wear resistant coating. As it is anticorrosive, thiscomposite can be used as anti-corossive coating on wrist watches , brass madeshow pieces etc to enhance their longibity. Mechanical properties of DLNmaterial along with the low refractive index and higher transparency comparedwith other thin film material makes DLN an attractive option for choosing DLNas a protective coating 50. In DLN, the highest physical limits ofmechanical, electronic and “sensor” properties can be combined and thus smartfuture material can be constructed 1. T.S. Santra et al reported DLN filmshave their unique number of structural, mechanical and tribological propertieswhich are quite similar with MEMS material.
Due to these unique properties ofDLN films, these are highly applicable in MEMS/NEMS devices. The highmechanical properties of DLN films make it applicable for design of highfrequency resonator and comb deriver for sensing and actuating applications.DLN film is a biocompatible material So,we can use DLN films for detection of bio-molecules in biological research anddisease diagnosis 17. Due to itsinfrared transparency, this can be used as anti-reflective coating on solarcell, glass etc. Sukhendu Jana et al 73 reporteddiamond-like nanocomposite filmbehaves as a dielectric medium. DLN thin film based MIM capacitor isapplicable for high capacitance and high frequency operation.
Thus DLN thin film based MIM capacitor has greatpotential for use in electrical/ electronic circuit. It has already beenreported that DLC are used for optical wave guiding sensing systems 74,transistors 75 and high tempeature sensing upto 600 0C 76. AsDLN is a improved version of DLC, So, there is a possibility to use DLN for thesame purpose. Diamond film grown on p-Sisubstrates using MWPECVD technique 77-79 may be used as antenna for harsh environment in aviation application.
