dc.description.abstractThis research aims to produce and develop semiconducting thermoelectric materials for thermoelectric generators in aerospace applications. In this context, ZnAlGeO powders were synthesized via the sol-gel method using precursor materials and a 20% toluene solution in ethanol as the solvent. Glacial acetic acid was added to accelerate gel formation. The pH and turbidity values of prepared solutions were measured using a pH meter and turbidimeter. After gelation, the obtained xerogel was dried at 200 degrees C for 9 h to remove moisture and undesired gases. Dried powders were calcined at 600 degrees C for 4 h in air, resulting in final ZnAlGeO materials. The pellets underwent thermal processing for 36 h at a temperature of 1350 degrees C, targeting the production of bulk samples within the n-type semiconductor category. Extensive characterization, including thermal, structural, microstructural, and thermoelectric properties, was conducted using various techniques such as DTA-TG, FTIR, XRD, XPS, SEM, and thermoelectric measurement devices. The study concludes that the produced semiconducting ceramic materials exhibit efficiency for thermoelectric generator production. Zn1-x-yAlxGeyO (x = 0.02, 0.04, and y = 0.02, 0.04) powders were synthesized by sol-gel method and densified under high-pressure cold pressing.Effects of dual doping on thermoelectric properties of Zn1-x-yAlxGeyO (x = 0.02, 0.04, and y = 0.02, 0.04) were investigated.Thermoelectric performances of Zn1-x-yAlxGeyO (x = 0.02, 0.04, and y = 0.02, 0.04) are enhanced by dual doping.Promising Zn1-x-yAlxGeyO (x = 0.02, 0.04, and y = 0.02, 0.04) oxide materials for energy harvesting and conversion technologies, particularly in aerospace applications.en_US
