Anisotropic magneto resistances and intrinsic adiabatic transport featuresare generated on quantum Hall samples based on an (Al,Ga)As/GaAsheterostructure with alloyed Au/Ge/Ni contacts. We succeed to probe themicroscopic origin of these transport features with a cryogenic scanning forcemicroscope (SFM) by measuring the local potential distribution within thetwo-dimensional electron system (2DES). These local measurements reveal thepresence of an incompressible strip in front of contacts with insulatingproperties depending on the orientation of the contact/2DES interface linerelatively to the crystal axes of the heterostructure. Such an observationgives another microscopic meaning to the term 'non-ideal contact' used incontext with the Landauer-B\"uttiker formalism applied to the quantum Halleffect.
