Terminal group engineering of Ti3C2Tx MXene on thermal emitter performance

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Март 12, 2025

Ti3C2Tx MXene has emerged as a promising material for diverse nanophotonics applications. In this study, we investigate how terminal groups (–F, –O–, –OH) influence the performance of planar thermal emitter with VO2/SiO2/Ti3C2Tx structure. By examining four variants across 2–20 µm spectral range, demonstrate that hysteresis loop threshold temperature remains constant all types due to VO2 phase change material. The average differential emissivity (Δε) between semiconductor and metallic states varies significantly group composition. VO2/SiO2/Ti3C2F2 structure exhibits highest Δε = 0.42, while VO2/SiO2/Ti3C2(OH)2 shows lowest 0.33. remaining structures; VO2/SiO2/Ti3C2 VO2/SiO2/Ti3C2O2, intermediate values 0.41 0.38, respectively. These findings establish foundation controlling in applications such energy harvesting, thermophotovoltaics, radiative cooling systems. ability tailor emission through engineering presents opportunities designing tunable photonic devices precise control capabilities next-generation management
