About Paper:

As the miniaturization of electrical devices progresses without sacrificing computational power, the importance of effective thermal management is becoming more critical. One way of controlling the heat produced in these devices is to use materials with high electrical and thermal conductivity. One such candidate is MXenes, a new family of two-dimensional compounds that consist of transition metal carbides, nitrides, or carbonitrides. Its characteristics are highly dependent on the synthesis procedures and comprised elements. While much research has been conducted to investigate the properties of Titanium-based MXenes to understand energy transfer within the material, no studies have investigated the thermal energy transport of Tantalum-based MXenes, as it is a material that has been synthesized recently. This project aims to identify the pure temperature-dependent thermal conductivity of Tantalum-based MXenes and compare it to Titanium-based MXenes. Samples are prepared on gold substrates, and micro-Raman thermometry is utilized to correlate Raman scattering shift peaks and temperature rise in the material. A heat transfer model is solved to extract the in-plane thermal conductivity. This analysis also yields insight into impurities, grain boundaries, and other phenomena within the thin film. The understanding of energy transport within MXenes is crucial for its utilization in complex environments with varying temperatures and to enhance its overall performance.
