SnO2 nanoparticles display a pseudo‐negative‐photoconductivity (PsdNPC) effect, which shows that their resistance increases under light irradiation via a heating effect. The PsdNPC originates from intensive electron scattering of the nanoamorphous surface state of the SnO2 nanoparticles, resulting in a small inner current and a large absorption of moisture, leading to a large surface current. Graphene...
A pseudo‐negative‐photoconductivity (PsdNPC) effect of SnO2 nanoparticles is reported by Y. Gao and co‐workers on page 3525. Combined with a light exciting effect, photoelectric logic gates are fabricated. The PsdNPC originates from intensive electron scattering of the nanoamorphous‐surface‐state of the SnO2 nanoparticles, resulting in a small inner current and a large absorption of moisture in the...
