抄録

We demonstrate a method for locally probing the electronic states in the quantum Hall regime utilizing a side-coupled quantum dot positioned at an edge of a Hall bar. By measuring the tunneling of electrons from the Hall bar into the dot, we acquire information on the local electrochemical potential and electron temperature. Furthermore, this method allows us to observe the spatial modulation of the electrostatic potential at the edge state due to many-body screening effect.
