Temperature-Dependence of Electronic States in (Tase4)(2)I
Giorgio Margaritondo, Helmuth Berger
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 consisten ...
1995Indirect-Gap Alxga1-Xas and Its Similarity to Gap
We report on luminescence, transmission and luminescence excitation measurements on indirect-gap AlxGa1-xAs in the composition range 0.42 less than or equal to x less than or equal to 0.86. The phonon coupling strength in transitions of bound excitons is i ...
1995Localized Electronic States and the Superconducting Gap in Bi2sr2cacu2o8+Y
Angle-resolved photoemission data taken on some Bi2Sr2CaCu2O8+y single crystals exhibit the formation of a superconducting gap in the absence of a quasiparticle normal state band. We observe the opening of the superconducting gap in the same regions of the ...

Giorgio Margaritondo, Helmuth Berger
Using high energy resolution angle-resolved photoemission, we have measured both the superconducting gap and the photoemission superconducting condensate spectral area of Bi2Sr2Ca1Cu1O8+x as a function of temperature in two different locations of the Brill ...
