The atomic an. electron.c structure of graphen. syn.hesized on.commercially available cubic-SiC（001）/Si（001） wafers have been.studied by low en.rgy electron.microscopy （LEEM）, scan.in. tun.elin. microscopy （STM）, low en.rgy electron.diffraction.（LEED）, an. an.le resolved photoelectron.spectroscopy （ARPES）. LEEM an. STM data prove the wafer-scale con.in.ity an. un.form thickn.ss of the graphen. overlayer on.SIC（001）. LEEM, STM an. ARPES studies reveal that the graphen. overlayer on.SIC（001） con.ists of on.y a few mon.layers with physical properties of quasi-freestan.in. graphen.. Atomically resolved STM an. micro-LEED data show that the top graphen. layer con.ists of n.n.meter-sized domain. with four differen. lattice orien.ation. con.ected through the 〈110〉-directed boun.aries. ARPES studies reveal the typical electron.spectrum of graphen. with the Dirac poin.s close to the Fermi level. Thus, the use of techn.logically relevan. SiC（001）/Si（001） wafers for graphen. fabrication.repre-sen.s a realistic way of bridgin. the gap between.the outstan.in. properties of graphen. an. their application..
