The heterogeneous integration of materials offers new paradigms in many extreme applications, where single materials cannot solve the problem alone. Diamond has a plethora of superlative properties that make it attractive in a diverse array of applications, such as its unique combination of unrivalled thermal conductivity combined with high electrical impedance; single photon emission at room temperature; superlative acoustic wave velocity, and Debye temperature. Most of these properties are directly related to diamond’s atomically dense lattice of light carbon atoms, which has consequences such as difficulty in doping diamond n-type and low thermal coefficient of thermal expansion. This last property presents a significant problem for the growth of diamond on nondiamond materials as the linear coefficients of thermal expansion of other materials are often several times larger than diamond.

金刚石的异构集成

材料的异构集成在许多极端应用中提供了新的范式，在这些应用中，单一材料无法单独解决问题。金刚石具有众多最高级的特性，使其在各种应用中都极具吸引力，例如其无与伦比的导热性与高电阻抗的独特组合;室温下单光子发射;最高级的声波速度和德拜温度。这些特性大多与金刚石的轻碳原子致密晶格直接相关，具有金刚石 n 型难以掺杂和热膨胀热系数低等后果。最后一种特性对金刚石在非金刚石材料上的生长提出了一个重大问题，因为其他材料的线性热膨胀系数通常比金刚石大几倍。
