Thanks to a new research by undertaken by researchers at the University of Warwick, 1D nanoscale materials of atomic size, waste heat now be transformed to electricity in a much more efficient manner. The research ushers a new way of generating sustainable energy. The research, undertaken in collaboration with the Universities of Birmingham and Cambridge, the study has led to the observation that thermoelectric materials can be made most effective by shaping them in the form of thinnest nanowires possible.

Thermoelectric materials are used to harvest waste energy and for converting it into reusable electricity. Owing to this, these materials find extensive usage as an environment-friendly and renewable energy source. Researchers of the study suggest that in comparison to 3D materials, isolated nanowires are capable of conducting more electricity and less heat at the same time. Owing to these unique qualities, 1D nanoscale materials are capable of yielding exceptional efficiency when it comes to the conversion of heat to electricity.

The researchers were studying the crystallization of tin telluride in narrow carbon nanotubes as models for forming these materials in their lowest dimensional build. In a combined research, the researchers were able to not only find a direct link between the size of a model and a resulting nanowire structure, but also were able to demonstrate how the method can be applied for regulating the thermoelectric power of tin telluride of having a diameter of 1-2 atoms.

The research opens up an opportunity for the development of new varieties of thermoelectric generators but also for further research in the field of alternative materials for thermoelectrics. As the demand for both thermoelectrics with improved efficiency as well as miniaturized electronics, this study can provide viable resources.
