Article Synopsis
- The study examines how adsorbates affect the space-charge-limited current (SCLC) in ZnO nanowires by adjusting bias voltage, laser light, and ambient pressure.
- In dark and air conditions, surface adsorbates deplete free carriers, with electrons from the electrode being the main contributors to electron transport.
- When exposed to laser illumination, the current-voltage behavior changes from linear at low voltages to superlinear at higher voltages, indicating that SCLC arises from the desorption of surface molecules.
