摘要：
We monitored the femtosecond-laser-induced lattice dynamics in PbSe quantum dots by ultrafast electron diffraction. The electron-phonon coupling didn't show phonon bottleneck. And lattice dilation exhibited unusual features. Heat transport to the substrate deviated significantly from Fourier's Law.
