Two dimensional crystals with strong interactions between layers has attracted increasing attention in recent years in a variety of fields. In particular, the growth of single layer of oxide materials (e.g. MgO, CaO, NiO and MnO), over metallic substrates were found to display different physical properties than their bulk. In this study, we report on physical properties of single layer of metallic oxide materials and compare their properties with their bulk and other two dimensional (2D) crystals. We found that the planar structure of metallic monoxides are unstable instead the buckled structure are thermodynamically stable. Also, the 2D-MnO and NiO exhibit different magnetic (ferromagnetic) and optical properties than their bulk whereas band gap energy and linear stiffness found to be decreasing from NiO to MgO. Our findings provide novel insight into oxide thin-film technology applications.

“…The application of thin layers for semiconductors developed in the form of transparent conductive oxides (TCO), capacitors, diodes, transistors and sensors. Application TCO develop rapidly and has been applied to electronic devices such as LCD TVs, Plasma TVs, organic electroluminescence (EL), for example touch screen monitors on automatic teller machine (ATM), ticket vending machines were installed in train stations, car navigation systems, handheld game consoles, mobile phones, and electrodes in solar cells [10][11][12][13][14]. SnO2 attractive for development because it is transparent to light (the energy gap 3.6 eV) [15], obstacles electricity is low, and has chemical stability is, the price is cheap, is responsive to a number of gas, durable, and requires only a simple electronic device in its application [16].…”

The effect of ageing on properties of nickel oxide thin films deposited using spray pyrolysis technique was the focus of this study. Freshly prepared and aged nickel oxide films were successfully deposited by spray pyrolysis technique on a glass substrate at 350°C. The morphological, elemental, structural and optical properties of two different films were studied. The surface morphology was studied using field emission gun scanning electron microscope. The X-ray diffraction shows that both freshly prepared and aged films have a polycrystalline cubic structure with a preferred orientation along the (1 1 1) and (2 0 0) planes. Optical studies show a high transparency in the visible and near infrared regions. The band gap grew with ageing from 3.60 eV to 3.70 eV. The optical constant including the refractive index and extinction coefficient reduced with ageing. Based on the result obtained, the prepared sample can be used as the absorber layer of solar cells.The findings may open new frontiers in affordable and efficient solar cell fabrication in developing countries.
