Giant Manipulation of Phonon Hydrodynamics in Ferroelectric Bilayer Boron Nitride at Room Temperature and Beyond

Abstract: Phonon hydrodynamics is an intriguing thermal transport mechanism that offers a great opportunity for phonon manipulation and thermal management. For decades, it has been believed that phonon hydrodynamics occurs only at very low temperatures, until very recently, it was confirmed that phonons can efficiently flow in low-dimensional materials at room temperature. However, to date, no study has been reported on the manipulation of phonon hydrodynamics at room temperature via reversible methods such as an extern… Show more

“…As depicted in Fig. 5(d), the difference in charge density (DCC) under the influence of the electric field, represented as Δ ρ = ρ ( E f ) − ρ ( E 0 ) 49 illustrates the charge redistribution prompted by external factors. This charge polarization is contingent upon the strength and direction of the electric field.…”
