Researchers have developed a new material with potential for highly efficient conversion of waste heat to energy by introducing twisted layers in ferecrystals, a distinctive class of misfit layered compounds (MLCs)

An example of 2D natural superlattice structured materials.

The concept of "Twisting Layers" in solid-state physics refers to a novel approach to enhancing thermoelectric materials, which can convert waste heat into electricity. This breakthrough is significant because thermoelectric materials have the potential to improve energy efficiency in various applications by harvesting otherwise lost heat energy.

This twisting can create unique electronic and phononic properties, including:

1. Enhanced Electron Transport: The twist creates electronic band structures that favor high electrical conductivity.
2. Reduced Thermal Conductivity: The misalignment disrupts the flow of heat-carrying phonons, reducing thermal conductivity without compromising electrical conductivity.
