When the YBCO growing on the SrTiO3 substrate tilt extensionally, it will make aα-Angle between the surface nonnals of YBCO film and the c axis of YBCO. If the laser light incidence the surface of the YBCO along the z axis, the z axis with a laser induced thermoelectric voltage produce. The thermoelectric material is called atom layer thermoelectric materials. This laser induced thermoelectric voltage (LITV) devices has a fast response (from ns to ps), response spectrum broad (spectral range from uv to infr...
