Abstract
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-μm laser and with a 10.6-μm 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 ≊0.58 eV and its recombination rate is lower than 2× .
