Research Abstract |
Type-II ZnSe-ZnTe superlattices with DSB structure show light modulation effects. The superlattices consist of two kinds of period and have two fundamental states at, for instance, 1.8 and 2.1 eV that depend on the structure at 8 K. The samples the substrates of which are removed a part (about 1 mmφ) transmit a little the light of the He-Ne laser (1.96 eV). The intensity of the transmitted light increases by about 10% under exposure to laser lights the photon energy of which is higher than 1.96 eV.
