Abstract

The integration of quantum emitters in semiconductor nanowires offers appealing prospects for quantum optics and quantum information applications. Here, we study the visible emission from metal-organic vapour phase epitaxy (MOVPE) zinc oxide nanowires. We show that the nanowires frequently incorporate native red-emitting colour centres at about 650~nm, in the form of small ensembles exhibiting photon antibunching, down to individual emitters. Additional post-treatment can yield modification of the number and the optical properties of the emitters, as well as generate near-infrared emitters (~780nm). Our results could be used for the realisation of guided quantum sources deterministically integrated in hybrid devices.

氧化锌外延纳米线中的红色和红外色心。

量子发射体在半导体纳米线中的集成为量子光学和量子信息应用提供了诱人的前景。本文研究了金属-有机气相外延氧化锌纳米线的可见光发射。我们发现，纳米线经常在约650~nm处包含原生红色发射色心，以显示光子反聚束的小集成形式，直至单个发射器。额外的后处理可以改变发射体的数量和光学性质，并产生近红外发射体（~780nm）。我们的结果可用于实现在混合器件中确定性集成的引导量子源。

期刊介绍： The journal aims to publish papers at the forefront of nanoscale science and technology and especially those of an interdisciplinary nature. Here, nanotechnology is taken to include the ability to individually address, control, and modify structures, materials and devices with nanometre precision, and the synthesis of such structures into systems of micro- and macroscopic dimensions such as MEMS based devices. It encompasses the understanding of the fundamental physics, chemistry, biology and technology of nanometre-scale objects and how such objects can be used in the areas of computation, sensors, nanostructured materials and nano-biotechnology.
