摘要：

A model is developed to explain the temporal evolution of the laser-induced transverse thermoelectrical response in bismuth films. The effect is studied with a 1.064-mum laser and with a 10.6-mum laser. The qualitative difference of the film response to each wavelength is evidence of the existence of a metastable band in bismuth. Its energy is almost-equal-to 0.58 eV and its recombination rate is lower than 2 x 10(7) S-1.
