THE ELECTRONIC-STRUCTURE OF TL2BA2CAN-1CU NO2N-FILMS(4(N=1,2) THIN)

The electronic structure of Tl2Ba2CuO6 and Tl2Ba2CaCu2O8 thin films ha s been investigated by the linearized augmented plane wave method. On the basis of the results of the energy band structure calculation for each film, total and local partial densities of electronic states have been calculated. Also, theoretical calculation of x-lay emission OKal pha and CuL(alpha) spectra have been performed. Dependence of the elec tronic structure and x-ray emission spectra on the number of CuO2 laye rs in the film unit cell is analyzed.
