间接激子是在空间分离的层中的电子和空穴的束缚态。二维间接激子可以在包含双量子威尔斯或原子级薄半导体的异质结构中光学地产生。我们从理论上研究了这种玻色准粒子通过纳米压缩的传输.我们表明,量子输运现象,例如,电导量子化、单缝衍射、双缝干涉和塔尔博特效应在间接激子系统中是实验上可实现的。我们讨论了这些现象和它们在电子设备中的对应物之间的相似性和差异。
An indirect exciton is a bound state of an electron and a hole in spatially separated layers. Two-dimensional indirect excitons can be created optically in heterostructures containing double quantum wells or atomically thin semiconductors. We study theoretically transmission of such bosonic quasiparticles through nano- constrictions. We show that quantum transport phenomena, e.g., conductance quantization, single-slit diffraction, two-slit interference, and the Talbot effect, are experimentally realizable in systems of indirect excitons. We discuss similarities and differences between these phenomena and their counterparts in electronic devices.
