A physics rule to design aperiodic width-modulated waveguides for minimum phonon transmission with Bayesian optimizationAntonios-Dimitrios Stefanou, Xanthippi Zianni
- General Materials Science
Optimal aperiodicity that minimizes thermal conduction is of maximum disorder in the modulation profile of width-modulated nano-waveguides. The degree of disorder is quantified by the number of non-identical modulation units.
