Incorporation of resistors along with tunnel junctions leads to the suppression of the higher order tunneling processes. But can resistors be used instead of tunnel junctions? Some people say yes. We fabricate and test devices using Cr oxide resistors connected to various metal layers (Al, Au,Pt). The results are pointing to the "no" answer
	Very broad distribution of the resulting resistances is typical for this method of SET fabrication		The yield of the devices showing Coulomb blockade oscillations is typically very low

Two figures are showing Coulomb blockade in SETs with resistors: oscillation pattern (left) and charging diagram (right)
