This article highlights the history of the quantum Hall edge, focusing on the distinction between sharp and smooth edges. We then introduce an edge-tunneling geometry consisting of two orthogonal quantum wells wherein magneto-tunneling measurements at a cleaved-edge overgrown quantum Hall edge are made. Peaks in the tunnel conductance are shown to arise from momentum conserved tunneling into ...
