dc.description.abstract | In recent years, with the rise of energy transition, research on thermoelectric materials has become increasingly popular. Thermoelectric materials have the ability to convert waste heat generated by energy consumption into electrical energy, thereby reducing pollution to the Earth. Previous research has shown that graphene nanoribbons have great potential in the field of thermoelectric materials. Therefore, this paper aims to research the thermoelectric performance of hexagonal boron nitride nanoribbons, which have a lattice structure similar to graphene nanoribbons. Firstly, we construct models using a program and then vary the dimensions, tunneling rates, and temperatures to observe changes in electrical conductivity, Seebeck coefficient, power factor, and thermoelectric figure of merit. From the results, we find that hexagonal boron nitride nanoribbons not only have lower phonon thermal conductivity but also exhibit stable thermoelectric parameters. The power factor and thermoelectric figure of merit do not undergo drastic changes with variations in dimensions or environmental factors. | en_US |
