A precise model for calculating dependence of selfcatalyzed Ga (As, P) nanowires composition on growth parameters without any fitting parameters is proposed. It is shown that the Ga(As, P) nanowires composition does not depend on the growth rate at a fixed ratio of group V and group III atoms total fluxes. The results of modeling are in good agreement with the experimentally observed dependence of the Ga(As, P) nanowires composition on the ratio of the fluxes of As and P atoms.

Radiation from rotational transitions of CO molecules in distant galaxies creates a chaotic background with an intensity reaching 1000 Jy/sr at a wavelength of approximately 1 mm. This background will pose a serious problem, when measuring spectral distortions of the cosmic microwave background, in particular, the mu-distortion, which presumably has an intensity of less than ...

This work presents a comprehensive investigation into the temperature-dependent thermally stimulated conductivity and photoconductivity of vacuum-annealed thin films based on core–shell CdSe/CdS nanoplatelets passivated with oleic acid ligands. Controlled thermal annealing under vacuum conditions leads to a substantial increase in both dark and photoinduced conductivity, which is primarily attributed to partial desorption of the ligands. ...

InAsP-based nanoheterostructures are in great demand in mid-infrared photonics for telecom and sensing applications. While the vapor–liquid–solid grown nanowires have demonstrated the potential to control the crystal phase and vary the InAsP alloy composition in a wide range, the use of a foreign gold catalyst adversely affects their optoelectronic properties. Here we address the limitations ...
