摘要：
Generation of a terahertz radiation in alpha-Sn / Ge quantum wells by ultrashort laser pulses is studied. Existence of the alpha-Sn at room temperature is shown by Raman spectroscopy. Cardinal differences were found in the parameters of THz pulses generated in samples with quantum wells widths of 4 nm, 6 nm sign and in nanostructures with quantum wells widths of 8.5 nm, 10 nm. The observed changes in the polarization dependences of the electric field of the THz radiation generated in alpha-Sn/Ge nanostructures with changes in the width of quantum well going from 6 nm to 8.5 nm are associated with the transition from a normal band structure to an inverted one in these nanostructures.
