Spontaneously formed phonon frequency combs in van der Waals solid CrGeTe3 and CrSiTe3

Spontaneously formed phonon frequency combs in van der Waals solid CrGeTe3 and CrSiTe3

Abstract Optical phonon engineering through nonlinear effects has been utilized in ultrafast control of material properties. However, nonlinear optical phonons typically exhibit rapid decay due to strong mode-mode couplings, limiting their effectiveness in temperature or frequency sensitive applicat...
