What are the Main Challenges in Thermal Dissipation at the Nanoscale?
Several challenges arise when dealing with thermal dissipation at the nanoscale:
1. High Heat Density: Nanodevices often operate at high power densities, making it difficult to dissipate heat effectively. 2. Material Properties: At the nanoscale, materials exhibit different thermal properties compared to their bulk counterparts. This can affect thermal conductivity and heat capacity. 3. Interfacial Resistance: Thermal resistance at interfaces between different materials can significantly hinder heat flow. This is particularly challenging in heterogeneous nanostructures. 4. Quantum Effects: Quantum confinement and other quantum effects can alter the way heat is transported in nanomaterials.
