KAIST researchers have reported the detection of a
picosecond electron motion in a silicon transistor. This study has
presented a new protocol for measuring ultrafast electronic
dynamics in an effective time-resolved fashion of picosecond
resolution. The detection was made in collaboration with Nippon
Telegraph and Telephone Corp. (NTT) in Japan and National Physical
Laboratory (NPL) in the UK and is the first report to the best of
our knowledge.
