What Challenges Exist in Conductance Measurements?
Conductance measurements at the nanoscale present several challenges:
1. Contact Resistance: Making reliable electrical contacts at the nanoscale can be difficult, affecting the accuracy of measurements. 2. Thermal Effects: Heating due to high current can alter the conductance of nanomaterials, leading to erroneous results. 3. Quantum Effects: At the nanoscale, quantum effects like quantum tunneling and electron confinement become significant, complicating the interpretation of conductance data.
