Abstract
III-V compound semiconductor nanowires have shown great promise for the development of the next-generation optoelectronic devices such as lasers-LEDs, solar cells and photodetectors, owing to their nanoscale size, direct bandgap, and excellent optical and electrical properties. In particular, ordered nanowire arrays have the advantages such as controllability of nanowire size and position, high uniformity in diameter and length, flexibility in creating heterostructures in both axial and radial directions. Hence, through proper design and engineering of the geometrical parameters of nanowire arrays, their light absorption and carrier transport characteristics can be manipulated and-or enhanced for photodetector applications. In this project, based on the well-established metalorganic chemical vapour deposition (MOCVD) growth and advanced nano-fabrication-characterization research platform at the Australian National University, we aim to develop high performance indium arsenide nanowire materials and structures for shortwave infrared photodetector applications at room temperature. Through a combined optical-electrical simulation, we will design and fabricate a variety of InAs nanowire array photodetectors targeting the shortwave infrared spectral range from 1.7-3 microm, which is challenging for the current InGaAs based technology. Based on the optimised photodetector device structures, multiwavelength and-or flexible photodetectors will be designed and fabricated for enhanced shortwave infrared photodetection and imaging. The proposed research will advance the fundamental knowledge in the multidisciplinary fields of material science, device physics, photonics and nanotechnology, and directly contribute to the development of low cost, high performance shortwave infrared photodetector and camera technologies for a wide range of applications for transportation, communication, biology, defence, manufacturing industry and consumer electronics.
