A transverse Seebeck effect exceeding that in YBa2Cu3O7 has been obser
ved in ''off-c-axis'' grown Bi2Sr2CaCu2O8 films. The films were prepar
ed by pulsed laser deposition from Bi2Sr2CaCu2O8 targets and grown wit
h a tilt angle of 10 degrees between the film c-axis and the film surf
ace on off-axis cut SrTiO3 substrates. From the thermoelectric respons
e upon laser irradiation the anisotropy of the thermopower is estimate
