Check out our phonon engineering of boron nitride!

Nov. 10, 2021—Our recent work on isotopically engineered boron nitride was just published in Journal of Materials Research! With isotopic engineering, the phonon frequencies as well phonon lifetimes can be modified. While the lighter atoms (10-B) shift the phonon frequencies to higher values, the heavier atoms (11-B) red-shifts the phonon frequency. As such, the phonon polaritons supported by hexagonal and...
