Impact of thermal annealing on graphene devices encapsulated in hexagonal boron nitride
S. Engels, B. Terrés, F. Klein +6
We present a thermal annealing study on single-layer and bilayer (BLG) graphene encapsulated in hexagonal boron nitride. The samples are characterized by electron transport and Ram…
All-electrical time-resolved spin generation and spin manipulation in n-InGaAs
I. Stepanov, S. Kuhlen, M. Ersfeld +2
We demonstrate all-electrical spin generation and subsequent manipulation by two successive electric field pulses in an n-InGaAs heterostructure in a time-resolved experiment at ze…
Unambiguous determination of spin dephasing times in ZnO
Sebastian Kuhlen, Ralph Ledesch, Robin de Winter +7
Time-resolved magneto-optics is a well-established optical pump probe technique to generate and to probe spin coherence in semiconductors. By this method, spin dephasing times T_2^…
Electric field-driven coherent spin reorientation of optically generated electron spin packets in InGaAs
S. Kuhlen, K. Schmalbuch, M. Hagedorn +5
Full electric-field control of spin orientations is one of the key tasks in semiconductor spintronics. We demonstrate that electric field pulses can be utilized for phase-coherent…
