在超点阵的热运输被各种各样的散布声子的过程管理。为在 chalcogenide 超点阵提取异种接口的散布声子的贡献，单人赛水晶的双性人 ₂ Se ₃/In₂ 有最小化的缺点的 Se ₃(BS/IS ) 超点阵被分子的横梁取向附生在 fluorophlogopite 云母上准备。BS/IS 超点阵的跨飞机的进行热的性质被表明精确取决于时期厚度和超点阵的成分，在在热传导性的最小显示一条转线路从的地方对在超点阵的像波浪的声子运输像粒子。BS/IS 超点阵的热传导性的最小比内在的 BS 电影的低将近一个数量级。

英文摘要：

Thermal transport in superlattices is governed by various phonon-scattering processes. For extracting the phonon-scattering contribution of hetero-interfaces in chalcogenide superlattices, single-crystalline Bi2Se3/In2Se3 （BS/IS） superlattices with minimized defects are prepared on fluorophlogopite mica by molecular beam epitaxy. The cross-plane heat-conducting properties of the BS/IS superlattices are demonstrated to depend precisely on the period thicknesses and constituents of the superlattices, where a minimum in the thermal conductivity indicates a crossover from particle-like to wave-like phonon transport in the superlattices. The thermal-conductivity minimum of the BS/IS superlattices is nearly one order of magnitude lower than that of intrinsic BS film.
