Nonlinear bend resistance is studied in a six-terminal mesoscopic ballistic junction in the hot-electron regime. Non-equilibrium electrons are generated by a voltage drop across a quantum point contact (QPC) embedded in the current lead of an orthogonal cross junction. The barrier height of the QPC constriction is tuned by a large-area top gate electrode which covers junction ...
