To establish the presence and orientation of the proposed striped phase in ultra-high-mobility 2D electron systems at nu = 9/2, current path transport properties are determined by varying the separation and alignment of current and voltage contacts. Contacts aligned orthogonal to the proposed intrinsic striped phase produce voltages consistent with current spreading along the stripes; current driven along the proposed stripe direction results in voltages consistent with channeling along the stripes. Direct comparison is made to current spreading/channeling properties of artificially induced 1D charge modulation systems, which determines the 9/2 stripe direction.
