 CMP - EPFL\nThe cupric oxide CuO exhibits an insulating ground state with 
 a correlation-induced charge-transfer gap and antiferromagnetism. It is\, 
 in principle\, the most straightforward parent compound of the doped cupra
 tes\, and therefore has been theoretically studied as a model material for
  high temperature superconductivity.\nBulk CuO crystallizes in a low-symme
 try monoclinic form\, in contrast to the rocksalt structure typical of lat
 e 3d transition metal monoxides. It was recently synthesized by epitaxial 
 growth on SrTiO3 substrates in a higher symmetry tetragonal structure with
  elongated c-axis (Siemons et al. PRB 79\, 2009). Extrapolating the behavi
 or of other 3d transition metal monoxides\, this phase of CuO is predicted
  to have a much higher Neel temperature than its bulk counterpart. At beam
 line 7 of the Advanced Light Source\, we have grown tetragonal CuO thin fi
 lms by pulsed laser deposition and investigated their electronic structure
  by angle-resolved photoelectron spectroscopy (ARPES). These measurements 
 represent the first mapping of the band structure of this new material\, n
 ot available in bulk phase\, and will serve as a reference point for futur
 e doping experiments.
