Figure 8

(a) I-V curves comparison of as-prepared CdS nanosheet film to colloidal single-crystalline CdS nanoplate formed film on PET conductive substrate. Insets are the TEM of single-crystalline CdS nanoplates, bulk film picture (left) and SEM of as-prepared CdS nanosheet film, bulk film picture (right). (b) I-V curves of as-prepared CdS nanosheet film on flexible PET substrate with different degree of bending force (L/L0). Insets are the schematic bending degree and picture of bending. (c) Typical I-V curve of Ag electrode/CdTe nanosheet film/PET conductive substrate. Inset shows a digital photo and a cartoon of the measurement device. (d) Typical I-V curves of CdTe nanosheet film with and without illumination by 300 W Xe lamp. Inset is a digital photo of the device for lateral I-V measurement. (e) Photoconductivity response of bulk-sized CdTe nanosheet film on exposure to on/off white light at room temperature without bias voltage. (f) Response time and recovery time of photodetector.
