| Research Abstract |
Conventional time-resolved scanning tunneling microscopes(TR-STM) have so long laser repetition periods of ~1 μs that their signal level falls when ultrafast phenomena of time scales less than 1 ns are observed. To solve the problem, two new setups for TR-STM are proposed and confirmed the efficiencies. One of them allowed us to successfully measure decay process of the electron spins in a GaAs sample whose time scale is about 5 ps
