Optoelectronic Quantum Transport

We explore the optoelectronic quantum transport in nanoscale circuits. Hereby, ballistic, thermoelectric, quantized, and spin-related transport processes are equally explored in mesoscopic circuits as coherently controlled photocurrent- and conductance phenomena.

Recent Highlights 

Magnetic focusing of ballistic photocurrents on the nanoscale

Spatially resolved ballistic optoelectronic transport measured by quantized photocurrent spectroscopy

Quantum interference control of femtosecond, µA current bursts in single GaAs nanowires
