飞秒电子衍射为确定纳米尺度的弹性特性开辟了新的前景。我们报告了通过飞秒激光光激发在超薄(110)高度取向的铋薄膜中产生的相干声声子的检测。
Femtosecond electron diffraction opens new vistas for determining elastic properties at nanoscale. We report on the detection of coherent acoustic phonons generated via fs laser photoexcitation in ultrathin (110)-highly oriented films of Bismuth.
