“…Sample stacks 1–3 were inserted into a typical low-e coating of dielectric/metal/dielectric stack to see if the above effect remains potent . AZO is a nontoxic, robust, transparent conductive oxide commonly used in thin film displays and photovoltaic applications due to its high visible transmittance, low electrical resistance, and low cost, compared to ITO, for example .…”

As technology development drives the thickness of thin film depositions down into the nano regime, understanding and controlling the dewetting of thin films has become essential for many applications. The dewetting of ultra-thin Ag (9 nm) films with Ti (0.5 nm) adhesion and capping layers on glass substrates was investigated in this work. Various thin film stacks were created using magnetron sputtering and were analyzed using scanning electron microscopy/energy dispersive X-rays, Vis/IR spectrometry, and four four-point probe resistivity measurements. Upon annealing for 5 h in air at 250 °C, the addition of a 0.5 nm thick Ti capping layer reduced the dewet area by an order of magnitude. This is reflected in film resistivity, which remained 2 orders of magnitude lower than uncapped variants. This Ti/Ag/Ti structure was then deployed in a typical low-emissivity window coating structure with additional antireflective layers of AZO, resulting in a superior performance upon annealing. These results demonstrate an easy, manufacturable process that improves the longevity of devices and products containing thin Ag films.

“…As for the σ–σ * gap aroused by sp 3 hybrid structure can be as high as 5.5 eV, whereas the π–π * formed gap is linked to carbon atom content . Refraction index and bandgap are all closely related to the π state near the Fermi energy, which is determined by the sp 2 content in film . Therefore, according to the two‐dimension clusters physical model, bandgap (proportional to n ) is determined by the content of sp 2 carbon atoms and the interrelationship between π and π *.…”

In this work, the interrelation between the anti‐reflective property and the component, especially the sp2 content, was studied. The results showed that the refraction index n increased from 2.2 to 3.3 with the direct current negative bias increasing. The reflection result R successful fall by 11.9% because of the existence of hydrogenated amorphous carbon anti‐reflective coatings. Both the refraction index and reflectivity decreasing correspond to a more graphitic microstructure character. Moreover, the optical property evolution of the films was explained by the chemical vapor deposition mechanism based on the ion sub‐plantation model and two‐phase model.

Cooling and air-conditioning systems are responsible for the highest energy consumption in buildings located in hot areas. This high share does not only increase the building energy demand cost but also increases the environmental impact, the topmost awareness of the modern era. The development of traditional systems and reliance on renewable technologies have increased drastically in the last century but still lacks economic concerns. Passive cooling strategies have been introduced as a successful option to mitigate the energy demand and improve energy conservation in buildings. This paper shed light on some passive strategies that could be applied to minimise building cooling loads to encourage the movement towards healthier and more energy-efficient buildings. For this purpose, seven popular passive technologies have been discussed shortly: multi-panned windows, shading devices, insulations, green roofing, phase change materials, reflective coatings, and natural ventilation using the windcatcher technique. The analysis of each strategy has shown that the building energy could be improved remarkably. Furthermore, adopting more passive strategies can significantly enhance the building thermal comfort even under severe weather conditions.
