Zn Impurities in BiSrCa(CuZn)O II - Temperature Induced Spectral Change

Following the preceding paper, which shows significant electronic structure evolution with Zn impurities, we report enhanced temperature induced spectral change in Zn doped Bi2212. We show intriguing systematic lineshape changes with temperature that persist to a very high energy scale- a result consistent with the idea that Zn enhanced the local charge inhomogeneity. We further made an attempt using ARPES to detect the stripe instability which is indirectly suggested by the strengthened 1/8 anomaly in Zn doped samples. We present our data and discuss their implications and uncertainties in the context of an earlier report by us and a critique of our work. We disagree with the central premise of ref. 3 that prior work of these authors has established the spectral weight to be temperature independent and all the temperature induced changes confined to an energy window of 3Delta. We show this to be in contradiction with an earlier claim and data by the same authors. On the other hand, we found significant uncertainty in our earlier interpretation of temperature induced spectral weight transfer- a fact most likely caused by sample aging. Despite this uncertainty in the evidence for stripes, our assertion of electronic inhomogeneity is consistent with new data presented in this and the preceding paper.
