ACS Appl Mater Interfaces
November 2024
Article Synopsis
- The study explores the synthesis of crystal-pure wurtzite gallium phosphide (GaP) nanowires containing gallium arsenide phosphide (GaAsP) quantum dots for emission in the visible-to-near-infrared spectrum (650-720 nm).
- The research details the growth processes, challenges faced, and solutions, leading to precise control over the shape and composition of the quantum dots, which enhances wavelength tunability.
- Results from low-temperature microphotoluminescence confirm the emission properties of the nanowires, demonstrating efficient carrier recombination and potential applications in quantum optics and nanophotonics.
Zincblende InAsP/InP Quantum Dot Nanowires for Telecom Wavelength Emission.
ACS Appl Mater Interfaces
May 2024
InAsP quantum dots (QDs) in InP nanowires (NWs) have been realized as a platform for emission at telecom wavelengths. These QDs are typically grown in NWs with the wurtzite crystal phase, but in this case, ultrathin diameters are required to achieve defect-free heterostructures, making the structures less robust. In this work, we demonstrate the growth of pure zincblende InAsP QDs in InP NWs, which enabled an increase in NW diameters to about 45 nm, achieved by employing Au-assisted vapor liquid solid growth in a chemical beam epitaxy system.
