Angle-resolved photoemissions studies were conducted on single-crystal (TaSe4)(2)I samples above and below the charge-density-wave transition temperature (T-CDW) of 260 K. We observed a shift of the leading photoemission edge between 300 and 60 K consistent with resistivity measurements performed on the same sample: a band gap opens throughout the Brillouin zone below T-CDW. However, several aspects of the data are difficult to reconcile with any standard model. RI Margaritondo, Giorgio/B-1367-2008

Abstract
Angle-resolved photoemissions studies were conducted on single-crystal (TaSe4)(2)I samples above and below the charge-density-wave transition temperature (T-CDW) of 260 K. We observed a shift of the leading photoemission edge between 300 and 60 K consistent with resistivity measurements performed on the same sample: a band gap opens throughout the Brillouin zone below T-CDW. However, several aspects of the data are difficult to reconcile with any standard model. RI Margaritondo, Giorgio/B-1367-2008File in questo prodotto:
