在强δ掺杂（1D）超晶格中产生负微分电阻的优化微型间隙
Optimized minigaps for negative differential resistance creation in strongly delta-doped (1D) superlattices
摘要：
“原子锯法”利用二维（2D）量子阱超晶格中的位错通道来创建周期性滑移层和一维（1D）量子线超晶格。这种空间结构的样品上的允许的能量的影响进行了分析的情况下，GaAs d掺杂超晶格。如果它们足够大，则出现在1D能带结构中的各种微型间隙可能是这些系统中存在具有高临界电流的负微分电阻（NDR）的原因。其目的是确定在样品参数方面的微型间隙的演变，并获得确定NDR可能出现的2D和1D结构特征的方法。
英文摘要：
The "atomic saw method" uses the passage of dislocations in two-dimensional (2D) quantum-well superlattices to create periodic slipping layers and one-dimensional (1D) quantum wire superlattices. The effects of this space structuring of the samples on the allowed energies are analysed in the case of GaAs d-doped superlattices. If they are sufficiently large, the various minigaps appearing in the 1D band structure could be responsible for the presence of negative differential resistance (NDR) with high critical current in these systems. The purpose is to determine the evolution of the minigaps in terms of the sample parameters and to obtain the means to determine both the 2D and 1D structural characteristics where NDR could appear.
