                         SnTe quantum well in the temperature range of 1.9100 K. The 
                         negative photoconductivity effect is observed for temperatures 
                         below 4 K, and it is strongly dependent on the light wavelength. A 
                         systematic analysis of the photoconductivity indicates that the 
                         origin of the negative photoconductivity is not related to the 
                         topological surface states but rather to the reduction of carrier 
                         mobility when the SnTe quantum well is illuminated with energies 
                         above 2 eV.",
