TL;DR: In this paper, the optical constants of the nanocomposite films were determined from spectroscopic ellipsometry measurements and were modeled using the Maxwell-Garnett effective medium theory, and the particle size dependence of the free electron absorption was included according to the limited electron mean free path effect using a broadening parameter A=0.16 determined from the comparison of the measured spectra with transmission electron microscopy micrographs.

TL;DR: In this article, the evolution of optical and microstructural properties as a result of annealing over a broad temperature range from room temperature up to 900°C was studied.

TL;DR: In this article, a micro-scratch test was used to evaluate the adhesion of amorphous hydrogenated silicon nitride (SiN 1.3 ) and oxide (SiO 2 ) films on polycarbonate and on silicon substrates.

TL;DR: In this paper, the structural arrangement of the sp2 phase in amorphous unhydrogenated carbon nitride (a•CNx) films and its effect on their physical properties are investigated.

TL;DR: In this article, a zinc oxide (ZnO) is proposed as a suitable material for the construction of hybrid solar cells, which can combine the merits of both organic and inorganic semiconductors and thus become low-cost alternatives to current PV cells.
