Pentagonal nanowires from topological crystalline insulators: a platform for intrinsic core-shell nanowires and higher-order topology
Ghulam Hussain, Giuseppe Cuono, Piotr Dziawa +12
We report on the experimental realization of Pb1-xSnxTe pentagonal nanowires (NWs) with [110] orientation using molecular beam epitaxy techniques. Using first-principles calculatio…
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…
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 doping on the intersubband absorption in Si- and Ge-doped GaN/AlN heterostructures
A. Ajay, C. B. Lim, D. A. Browne +5
In this paper, we study band-to-band and intersubband characteristics of GaN/AlN heterostructures (planar and nanowires) structurally designed to absorb in the short-wavelength inf…
