title = "Imaging electron interferometer",
abstract = "An imaging electron interferometer was created in a two-dimensional electron gas (2DEG) using a liquid-He cooled scanning probe microscope (SPM). Electron waves emitted from a quantum point contact (QPC) return to the QPC along two paths: reflection from a concave mirror formed by a gate, and backscattering from the depleted disc underneath the charged SPM tip. Interference of these waves when they return to the QPC produces strong interference fringes in images of electron flow. A quantum phase shifter is formed by moving the mirror via its gate voltage - the fringes move a corresponding amount. The coherent fringes are robust to thermal averaging when the lengths of the two paths are within lT = vF/πk BT of each other.",
