| Abstract;Recent studies which measured the tunneling conductance into underdoped cuprates found an unexpected spatial modulation at higher bias voltages. In this letter, a simple model is proposed as a possible explanation for the checkerboard pattern of in the hole density. We starts from the assumption of enhanced hole densities localized in the vicinity of acceptors and examines the consequences of short range correlations in the positions of the acceptors, e.g. the Na-ions in Ca2-xNaxCuO2Cl2. These result can lead to a structure factor in qualitative agreement with experiment. |
