Introductory Chapter: Basic Theory of Magnetron Sputtering

Magnetron sputtering is a highly versatile thin film deposition technique for coating films with excellent adhesion and high density. A type of physical vapor deposition (PVD) coating technology, magnetron sputtering is a plasma-based coating process where a magnetically confined plasma is created near the surface of a target material From Wikipedia, the free encyclopedia High-power impulse magnetron sputtering (HIPIMS or HiPIMS, also known as high-power pulsed magnetron sputtering, HPPMS) is a method for physical vapor deposition of thin films which is based on magnetron sputter deposition

High power impulse magnetron sputtering (HiPIMS) is well known in modern physical vapor deposition (PVD) owing to its high peak power density, high degree of ionization, high plasma density and hence high ion flux towards the substrate that allows ones to deposit high quality thin films in comparison with conventional magnetron sputtering technology By utilizing Reactive Co-Sputtering of two target materials such as Silicon and Titanium with dual Magnetron Sputtering, the refractive index or shading effect of the glass can be carefully and precisely controlled on applications ranging from large scale surfaces such as skyscraper architectural glass to sunglasses various thin film applications. Nevertheless, few studies on nano-structured carbon materials obtained using magnetron sputtering 17-19 and even fewer for graphene synthesis20 have been reported so far.

Today, magnetron sputtering often outperforms other techniques used for the deposition of coatings of industrial interest. The conventional magnetrons, developed in the early 1970s, were an important step in overcoming the limitations of the early sputtering process, which has been known and used for many years despite its limited industrial. Smart windows are a perfect innovative example of technology that reduces our energy dependence and our impact on the environment while saving on the economical point of view. With the use of vanadium dioxide (VO2), a thermochromic compound, and this, as a thin coating, it would in fact be possible to control the sun's transmission of infrared light (heat) as a function of the surrounding.
