Abstract
Ballistic transport of hot electrons in a quantum Hall edge channel is attractive for studying the electronic analog of quantum optics, where the edge potential profile is an important parameter that governs the charge velocity and scattering by longitudinal-optical (LO) phonons. Here, we use a parallel double gate to control the electric field of the edge potential and investigate the ballistic length of the channel by using hot-electron spectroscopy. The ballistic length is significantly enhanced by reducing the LO phonon scattering rate in the tailored potential.
