Description
関連ワークでは、CNTの自由端の接触抵抗は、Cu−CNT−Siインターフェースで全体の抵抗の〜90%を構成することが示された(J. Xu and T.S. Fisher, “Enhancement of thermal interface materials with carbon nanotube arrays,”International Journal of Heat and Mass Transfer, vol.49, pp.1658-1666, May 2006 参照)。インジウムはんだ合金を使用するCNT自由端の金属結合(”Indium Assisted Multiwalled Carbon Nanotube Array Thermal Interface Materials”2006 IEEE proceedings 参照)は、乾燥したインターフェース対大きさのオーダーで熱抵抗を軽減することが示された。
