Coherent Longitudinal Acoustic Phonon Approaching THz Frequency in Multilayer Molybdenum Disulphide
Coherent longitudinal acoustic phonon is generated and detected in multilayer Molybdenum Disulphide (MoS(2)) with number of layers ranging from 10 to over 1300 by femtosecond laser pulse. For thin MoS(2), the excited phonon frequency exhibits a standing wave nature and shows linear dependence on the...
