Abstract
We have observed strong transport anisotropies in magneto-transport experiments in the two-dimensional electron system of a SiGe heterostructure. These effects occur in tilted magnetic fields where two neighboring Landau levels with opposite spin are close to half filling. We propose that the observed anisotropies may be due to the formation of a unidirectional stripe phase formed by two energetically coinciding Landau levels.
