Deformation & phonons

Phonons play an important role in transporting energy and governing the efficiency of nanomaterials in practical applications, such as in thermoelectric energy conversion. The objective of this study is to identify how deformation and material heterogeneity couple with phonons and modulate its energy carrying capacity.
