Figure 4From: Tunneling times of acoustic phonon packets through a distributed Bragg reflectorTunneling times. (a) The dwell time tD (in μ s) and (b) the transmission time τt and free time tf (in μ s) plotted as a function of the acoustic phonon frequencies (in GHz). (c) Theoretical and experimental transmission coefficients (in dB) plotted as a function of the acoustic phonon frequencies (in GHz).Back to article page
