Cross-scale Raman thermometry: Bridging equilibrium-to-non-equilibrium thermal dynamics from micro-devices to single-molecule junctions

Caption

This graphical summary illustrates the comprehensive framework for cross-scale Raman thermometry, which bridges the gap between macroscopic thermal management and molecular-level energy dynamics. The progression moves from far-field Micro-Raman imaging of semiconductor hotspots (~1 µm) to near-field Tip-Enhanced Raman Spectroscopy (TERS) capable of probing single-molecule junctions (~1 nm). The framework highlights the transition from classical thermal equilibrium to non-equilibrium states governed by quantum fluctuations where traditional definitions of temperature no longer apply. The lower section depicts the integration of AI-driven spectral analysis and databases, envisioning an automated ecosystem for the intelligent thermal design of next-generation nano-electronics
