절연 박막에 대한 표면 포논 폴라리톤의 나노스케일 에너지 전달 특성
윤국현(Kuk Hyun Yun),이봉재(Bong Jae Lee),이성혁(Seong Hyuk Lee) 대한설비공학회 2022 대한설비공학회 학술발표대회논문집 Vol.2022 No.6
This study aims to numerically analyze the energy transport of surface phonon polaritons(SPhPs) in the thin dielectric film. It is important to analyze the heat transfer characteristics of SPhPs to improve the heat dissipation of semiconductors. The Boltzmann transport equation(BTE) is used to consider the ballistic energy transport of SPhPs. The various film lengths and thicknesses are also considered to analyze the heat transfer performance. From the results, the temperature distributions are almost identical regardless of the film lengths owing to the long propagation length of SPhPs. The heat flux increases with the decrease of the film thickness due to the depth average assumption. The effective in-plane thermal conductivity also increases as the film length increases and thickness decreases, with the same tendency as theoretical results. It is confirmed that SPhPs can improve the thermal conductivity of bulk SiO₂ by about 29.2%.
