Abstract: Large transverse thermoelectric and photon-drag signals in the infrared have been previously observed in semimetal films of Bi and Sb evaporated at large angles with the substrate normal. In this work by analysing the behaviour of both signals versus the evaporation angle, the thickness and the radiation wavelength we can deduce a model for the anisotropy induced by the transverse evaporation.
