Abstract The nonisothermal cold crystallization behavior of intercalated polylactide (PLA)/clay nanocomposites (PLACNs) was studied using differential scanning calorimetry, polarized optical microscope, X‐ray diffractometer, dynamic mechanical thermal analysis, and Fourier transform infrared spectrometer. results show that both the temperature ( T cc ) melting point m PLA matrix decreases monotonously with increasing clay loadings, accompanied by decreasing degree crystallinity X c %) at low...
High-power GaN-based electronics are limited by high channel temperatures induced self-heating, which degrades device performance and reliability. Increasing the thermal boundary conductance (TBC) between GaN SiC will aid in heat dissipation of GaN-on-SiC devices taking advantage conductivity substrates. For typical growth method, there issues concerning transition layer at interface low-quality adjacent to interface, impedes flow. In this work, a room-temperature bonding method is used bond...
Thermal conductance at interface with weak van der Waals bonding can become larger than that strong covalent bonding.
Effective heat dissipation is critical for the performance and longevity of electronic devices. This study delves into intricacies thermal boundary conductance (TBC) between multilayer graphene silicon, scrutinizing its correlation with thickness. Employing a combination no-transducer time-domain reflection technique nonequilibrium molecular dynamics simulations empirical machine-learning based potentials, we discover an intriguing behavior: TBC initially increases thickness, but it...
Thermal switching provides an effective way for active heat flow control, which has recently attracted increasing attention in terms of nanoscale thermal management technologies. In magnetic and spintronic materials, the conductivity depends on magnetization configuration: this is magneto-thermal resistance effect. Here we show that epitaxial Cu/Co$_{50}$Fe$_{50}$ multilayer film exhibits giant magnetic-field-induced modulation cross-plane conductivity. The ratio reaches 150% at room...
The Seebeck and Peltier effects have been widely studied used in various thermoelectric technologies, including thermal energy harvesting solid-state heat pumps. However, basic applied studies on the Thomson effect, another fundamental effect conductors, are limited despite fact that allows electronic cooling through application of a temperature gradient bias rather than construction junction structures. In this article, we report observation giant appears owing to magnetic phase...

“Fifth generation and beyond” communication technologies have sparked considerable demand for polymer composite materials with low thermal expansion coefficients (CTE) dielectric loss under high operation frequency. However, the...
Abstract Understanding and controlling heat conduction in twisted transition‐metal dichalcogenides (TMDs) is crucial for thermal management TMDs semiconductor devices advancements their functions. Despite the significant tunability reported interlayer randomly multilayer TMDs, dependence of on twist angle remains unclear. In this study, twist‐angle‐dependent conductance bilayer WS 2 MoS initially assessed. As a result, decreases as between two stacked layers increases from commensurate to...
