What Challenges Exist in IV Characterization at the Nanoscale?
Characterizing nanoscale materials and devices presents unique challenges:
1. Contact Resistance: Making reliable electrical contact can be difficult due to the small size. 2. Noise: Electrical noise can significantly affect measurements at the nanoscale. 3. Thermal Effects: Heating can occur due to high current densities, affecting the measurement. 4. Material Variability: Nanoscale materials often exhibit significant variability, complicating analysis.
