Abstract

III-V compound semiconductor nanowires have drawn much attention as nanoscale building blocks for optoelectronic/photonic integration owing to their nanoscale size, excellent optical properties and strain relaxation ability enabling monolithic growth on lattice-mismatched substrates. In particular, highly-ordered nanowire arrays grown by selective area epitaxy technique have the advantages of controllability of nanowire size and position and thus high uniformity, critical for many device applications. With suitable wavelength ranging from 1.3 to 1.6 μm, InGaAs/InP quantum wells have been being widely used for optical communication applications. In this work, I will present our work on selective area growth of highly uniform InGaAs/InP multiple quantum well nanowire arrays by metalorganic chemical vapour deposition (MOCVD), and the demonstration of high speed, micro LED and photodetector arrays operating at telecommunication band, promising for the development of next generation highly integrated photonic/optoelectronic systems and building of the much anticipated metaverse.

III-V族化合物半導體納米線因其納米級尺寸、優異的光學性能和應變弛豫能力日益成為光電/光子集成的熱點構件。特別是通過選區外延技術生長的納米線陣列，因其具有納米線尺寸和位置可控的優點，可以實現對器件應用至關重要的高均勻性。我們知道，得益于其特殊的波長范圍(1.3-1.6 μm), InGaAs/InP 量子阱已被廣泛用于光通信。在此，我將介紹如何通過晶面生長控制實現基于金屬有機化學氣相沉積 (MOCVD) 的高度均勻的 InGaAs/InP多量子阱納米線陣列的選區外延生長，并展示通訊頻段的高速微型LED和光電探測器陣列器件，以用于打造下一代高度集成的光子/光電系統和備受期待的元宇宙。
