Abstract(in English) | The annealing optimal condition is searched of the c- and r-cut LiNbO_3(LNO) substrates. Heat treatment of c-cut is carried out in air for 5~12 hour at 700~950℃. Heat treatment of r-cut is carried out in air for 3~24 hour at 700~1050℃. In c-cut LNO substrates, the wavy step-terrace structure is observed at 1000℃ or more for 5 hour. At 800℃ or more for 12 hour. A 6.2nm high particulates appeared on the surface of the substrate. A number of particulates decrease at high temperature. In r-cut LNO substrates, It will the step become a form like a needle, if heat treatment time is 5 hour and fewer or temperature is 1000℃ over. At 700℃ and 800℃, a facet-like step and bunching step, and smooth step bunching step appear. At 900℃, the step like stairs and bunching step are observed. The Cr_2O_3 thin films are deposited by DC-RF magnetron sputtering method on r-cut LNO substrates. Uniaxial grains with the size of approximately 0.4μm in wide and longer than 0.4μm in length are observed. The 58nm deep slot occurred between grains. It was flat when measuring only the one grain surface. |
