Using the technique of photoluminescence imaging during electrical transport in crossed electric and magnetic fields, the rotation of the current flow direction has been observed. The rotation angle is identically the Hall angle. As a model system, a thin n-type GaAs layer in the regime of low-temperature impurity breakdown has been used, generating filamentary current patterns. The measurement of the Hall angle allows one to determine the mobility inside current filaments. [S0163-1829(98)05043-7].
