Effect of the nanowire diameter on the linearity of the response of GaN-based heterostructured nanowire photodetectors
Maria Spies, Jakub Polaczyński, Akhil Ajay +5
Nanowire photodetectors are investigated because of their compatibility with flexible electronics, or for the implementation of on-chip optical interconnects. Such devices are char…
Nanowire photodetectors based on wurtzite semiconductor heterostructures
Maria Spies, Eva Monroy
Using nanowires for photodetection constitutes an opportunity to enhance the absorption efficiency while reducing the electrical cross-section of the device. They present interesti…
Bias-controlled spectral response in GaN/AlN single-nanowire ultraviolet photodetectors
Maria Spies, Martien I. Den Hertog, Pascal Hille +6
We present a study of GaN single-nanowire ultraviolet photodetectors with an embedded GaN/AlN superlattice. The heterostructure dimensions and doping profile were designed in such…
Effect of the quantum well thickness on the performance of InGaN photovoltaic cells
L. Redaelli, A. Mukhtarova, S. Valdueza-Felip +7
We report on the influence of the quantum well thickness on the effective band gap and conversion efficiency of In0.12Ga0.88N/GaN multiple quantum well solar cells. The band-to-ban…
Design of broadband high-efficiency superconducting-nanowire single photon detectors
Luca Redaelli, Gabriele Bulgarini, Sergiy Dobrovolskiy +4
In this paper several designs to maximize the absorption efficiency of superconducting-nanowire single-photon detectors are investigated. Using a simple optical cavity consisting o…
