What Challenges Exist in Controlling Current at the Nanoscale?
Controlling current at the nanoscale presents several challenges, such as:
Quantum Effects: At the nanoscale, quantum effects become significant, leading to phenomena like tunneling and quantization of conductance. Thermal Management: Managing heat dissipation is critical due to the high current densities involved. Material Limitations: Developing materials that can sustain high currents without degradation is a challenge. Fabrication Precision: Achieving precise control over the fabrication of nanostructures is essential for predictable current flow.
