Local Density of States in Mesoscopic Samples from Scanning Gate Microscopy
M. G. Pala, B. Hackens, F. Martins +4
We study the relationship between the local density of states (LDOS) and the conductance variation in scanning-gate-microscopy experiments on mesoscopic structures as a charge…
Imaging Electron Wave Functions Inside Open Quantum Rings
F. Martins, B. Hackens, M. G. Pala +8
Combining Scanning Gate Microscopy (SGM) experiments and simulations, we demonstrate low temperature imaging of electron probability density in embedded mesoscopic q…
Effect of dephasing on the current statistics of mesoscopic devices
Marco G. Pala, Giuseppe Iannaccone
We investigate the effects of dephasing on the current statistics of mesoscopic conductors with a recently developed statistical model, focusing in particular on mesoscopic cavitie…
Statistical model of dephasing in mesoscopic devices introduced in the scattering matrix formalism
Marco G. Pala, Giuseppe Iannaccone
We propose a phenomenological model of dephasing in mesoscopic transport, based on the introduction of random phase fluctuations in the computation of the scattering matrix of the…
Two-dimensional hole precession in an all-semiconductor spin field effect transistor
Marco G. Pala, Michele Governale, Jürgen König +2
We present a theoretical study of a spin field-effect transistor realized in a quantum well formed in a p--doped ferromagnetic-semiconductor- nonmagnetic-semiconductor-ferromagneti…
Universal Rashba Spin Precession of Two-Dimensional Electrons and Holes
Marco G. Pala, Michele Governale, Jürgen König +1
We study spin precession due to Rashba spin splitting of electrons and holes in semiconductor quantum wells. Based on a simple analytical expression that we derive for the current…
