Ultrafast magneto-photocurrents as probe of anisotropy relaxation in GaAs
Christian B. Schmidt, Shekhar Priyadarshi, Klaus Pierz +1
We induce ultrafast photocurrents in a GaAs crystal exposed to a magnetic field by optical femtosecond excitation. The magneto-photocurrents are studied by time-resolved detection…
All-optically induced currents resulting from frequency modulated coherent polarization
Shekhar Priyadarshi, Klaus Pierz, Mark Bieler
We employ polarization-shaped ultrafast optical pulses to generate photocurrents which only arise if the optically induced coherent polarization is frequency modulated. This freque…
All-optically induced ultrafast photocurrents: Beyond the instantaneous coherent response
Shekhar Priyadarshi, Klaus Pierz, Mark Bieler
It is demonstrated that the non-instantaneous response of the optically induced coherent polarization tremendously influences the real-space shift of electronic charges in semicond…
