Extended Data Fig. 7: Longer time traces of the data shown in the main text.

From: Terahertz phonon engineering with van der Waals heterostructures

Extended Data Fig. 7

a, Phonon oscillation data identical to that in Fig. 1d but with a longer time window (device 1, WSe2/hBN/3LG, dhBN = 80.2 nm, at 77 K). b, Phonon oscillation data identical to that in Fig. 3c (device 3, WSe2/hBN/5LG, dhBN = 19.6 nm, at 77 K) is shown up to 300 ps.
