最近的实验表明，半导体介观结构的横向电流-电压特性具有惊人的整流效应，具有良好的应用前景。我们提出了一个简单的微观模型，它考虑到载流模式的能量依赖性，并解释了整流效应的相互作用，在系统中的完全量子化和准经典传输通道。它还建议设计一个弹道整流器与优化的整流信号和预测电压振荡，这可能会提供一个实验测试的机制考虑在这里。
Recent experiments on symmetry-broken mesoscopic semiconductor structures have exhibited an amazing rectifying effect in the transverse current-voltage characteristics with promising prospects for future applications. We present a simple microscopic model, which takes into account the energy dependence of current-carrying modes and explains the rectifying effect by an interplay of fully quantized and quasiclassical transport channels in the system. It also suggests the design of a ballistic rectifier with an optimized rectifying signal and predicts voltage oscillations which may provide an experimental test for the mechanism considered here.
