Abstract: The outstanding physical and thermoelectric properties that are exhibited by two-dimensional (2D) materials have gained resounding traction amongst scientists. Notably, 2D materials boasts great flexibility, atomically thin structures, and superior thermal management as opposed to their bulk material counterparts. Such properties demonstrate its potential in the development of state of the arts electronics. In particular, novel 2D materials such as the few-layered Bi2O2Se have been credited to have high air stability and ultra-fast carrier mobility. Furthermore, unlike other 2D materials, Bi2O2Se possesses good thermoelectric properties even at room temperature. The thermoelectric properties can be quantified using a Seebeck device. However, the structural characteristic of the material poses a significant challenge during the synthesis and device fabrication stages. And as a result, there is a lack of reliable thermoelectric data. Therefore, this study aims to optimize the process flow for the preparation of the novel 2D Bi2O2Se material as well as the Seebeck device. This will be achieved by testing out different techniques and parameters. The data obtained will then be reviewed to enhance the understanding of the thermoelectric properties of the novel 2D material.
