12. InP/InAsP Quantum Discs-in-Nanowire Array Photodetectors: Design, Fabrication and Optical Performance
Abstract : This thesis focuses on processing and electro-optical investigations of two- and three-terminal photodetectors based on large arrays of around three million n+-i-n+ InP nanowires with embedded InAsP quantum heterostructures for broadband detection. First, we investigated the optoelectronic behavior of two-terminal photodetectors under selective 980 nm excitation of the 20 axially embedded InAsP quantum discs in each of the nanowires. READ MORE
