| dc.description | Conventional energy sources are limited, and soon, these sources will be expected to have vanished, so to meet the energy requirement, it is necessary to look for different alternative energy generation systems. These sources should produce green and environmentally friendly energy so that environment won't get affected [1,2]. There are different kinds of green and environmentally friendly energy production systems, such as hydro power, wind power, solar power, piezoelectric, and thermoelectric power generation system. Among them, thermoelectricity is one of the cheap and environment friendly source of energy because it harvests wasted heat energy from the environment and converts it into useable electrical energy [[3], [4], [5], [6], [7], [8], [9], [10]]. It has been almost half a century since researchers are trying to improve the material's properties and making efforts to enhance the efficiency of thermoelectric power generation systems both in experimental and theoretical domains. The overall efficiency of material (both in power generation & refrigeration) is determined by a mathematical relation called (ZT) or figure of merit, which is dimensionless and given as (see Table 1). | |
| dc.description.abstract | In this manuscript, the thin films of Magnesium Selenide (MgSe) were synthesized on a glass substrate using a single-stage horizontal tube furnace (SSHTF) which is supposed to be the simplest and a cost-effective approach. Before the deposition of thin films, the substrate was cleaned using standard methods. A pellet was formed by taking an equal ratio (1:1) of magnesium (Mg) and selenium (Se) powders and then evaporating them at 700oC for 1 h. The flow rate of nitrogen gas (100 SCCM) was maintained during the deposition process to avoid unwanted oxygen. A number of samples were synthesized by varying the source to substrate distance, and some representative samples are chosen for this study. The post-growth samples were characterized using XRD, SEM, and Raman Spectroscopy. The thermoelectric potential of all samples was tested by a home-developed Seebeck system. We have observed some promising values of the Seebeck coefficient (7.175 × 10−5 V/°C) and power factor (6.35 × 10−8 Wm−1oC−2) at optimized source-to substrate distance. These encouraging results will open the door for MgSe-based thermoelectric research and further explore its power generation potential in the future. keywords: MgSe thin films, Source to substrate distance, Thermoelectric power generation, Vacuum tube furnace | |
