"Artificial atoms" in magnetic fields: Wave-function shaping and phase-sensitive tunneling
We demonstrate the possibility to influence the shape of the wave functions in semiconductor quantum dots by the application of an external magnetic field Bz. The states of the so-called p shell, which show distinct orientations along the crystal axes for Bz=0, can be modified to become more and more circularly symmetric with an increasing field. Their changing probability density can be monitored using magnetotunneling wave function mapping. Calculations of the magnetotunneling signals are in...[Show more]
