From: Assembly of PbTe/Pb-based nanocomposite and photoelectric property
The photoelectric performance measurement. (a) The current-voltage characteristics of the single PbTe/Pb nanostructure before and after laser irradiation at 300 K a Without light irradiation; b under the 532-nm wavelength, 1 × 10−3 W/cm2 laser irradiation; and c restoration without light irradiation again. (b) The current-voltage characteristics of PbTe/Pb nanostructure arrays before and after assembling the Zn x Mn1−xS nanoparticles at 300 K. The lower right insert figure gives the optical micrograph of the PbTe/Pb array device with molybdenum electrodes. d Without light irradiation; e under the 532-nm wavelength, 1 × 10−3 W/cm2 laser irradiation; f combined a spot of Zn x Mn1−xS nanoparticles under the 532-nm wavelength, 1 × 10−3 W/cm2 laser irradiation; and g combined sufficient Zn x Mn1−xS nanoparticles under the 532-nm wavelength, 1 × 10−3 W/cm2 laser irradiation.
