Data: Exploring Phonon Interference: Insights from a Nano-Scale Silicon Double Slit Atomistic Simulation

These resources offer a more detailed understanding of the phonon interference behaviour and help visualize the experimental setup, as well as the challenges encountered during simulation. The data presented here complement the theoretical discussion in the main manuscript and provide insights into the potential for future experiments and applications in nanotechnology, thermal management, and phonon-based devices. The frequency analysis as mentioned in the main publication and Figure S1 is being done for frequencies from 1THz to 6THz for the Geometric Case 1 with  Slit Length (A=4nm), Slit Distance (d=8,6nm), Slit Width (c=3nm).The geometry analysis is where the data for the main comparison and finally validation of the claim that phononic interference in a double slit setup behaves the same as the light case that Young implemented.
