“…So, an effective method of obtaining a high yield of high-quality morphology-tunable CdS nanowires needs to be put forward. Recently, novel method of fabrication CdS nanowire structures has been found, such as catalyst-free template method22, in situ growth using pulsed laser deposition on low temperature23, and assisted synthesis method24, and so on.…”

CdS is an important semiconductor used in optoelectronic devices. Simple techniques for growing CdS nanostructures are thus essential at a low cost. This study presents a novel method for growing singlecrystal n-type CdS nanowires on p-type CdTe films by thermal annealing in an H 2 S/N 2 mixed gas flow, which does not require the help of a catalyst or template. The formation process and growth mechanism of the nanowires are investigated. Well-dispersed whiskerlike CdS nanostructures are obtained at an appropriate annealing temperature and duration. We suggest that the stress-driving mechanism of nanowire formation may contribute to the growth of CdS nanowires, and that the evaporation of Te through the boundaries of the CdS grain seeds plays an important role in the sustainable growth of nanowire. In addition, CdS/CdTe heterojunction device is fabricated on Mo glass. The I-V characteristic of the heterojunction in dark shows typical rectifying diode behavior. The turn-on voltage can be regulated by annealing conditions. Meanwhile, the obvious photovoltaic effect is obtained on the in situ growth heterojunction prepared at low annealing temperature. Hence, this is a new fabricated method for CdTe-based materials in the field of energy conversion.CdS is a well-studied semiconductor with versatile properties, such as a direct band gap of 2.4 eV at room temperature, a high refractive index, excellent transport properties and good chemical and thermal stability. It has been used extensively in photovoltaic devices, light-emitting diodes in flat panel displays, transistors, and logic gates 1-3 . Low-dimensional CdS nanostructures, such as nanorods, nanowires, and nanotubes, have attracted increasing attention because of their superior optical, physical, electronic and catalytic properties compared with traditional thin film and bulk materials [4][5][6] . A wide range of applications for nanodevices and nanosystems based on these CdS nanostructures has recently been explored, including a thin film transistor fabricated on CdS nanoribbons 4 , and chemical vapor deposition (CVD) [15][16][17] . Although each of these methods has its own advantages, most involve a solution process or organic solvents 13,18 , and the reaction process is uncontrollable. The CVD method is known to be effective in the large-scale fabrication of CdS nanostructures. However, due to the high sublimation temperature of CdS powder, the growth temperature of CdS nanostructures is as high as 800 °C 12,19 , and the growth process requires the use of an Au catalyst 20 . Unfortunately, Au functions as an impurity, trapping electrons and holes in the nanostructure, and affecting the performance of the device. Templates, such as anodic aluminum oxide 9,21 , which are used to prepare nanowires, can also yield better CdS arrays. However, this method also needs Au catalyst to grow nanostructure 9 . So, an effective method

“…Initial nuclei were produced by vacuum deposition of thermally evaporated metals on the substrate to the mass thickness 0.5…2.5 nm and the following annealing of the substrate directly in vacuumed reactor by stepwise heating up to 500 °C for 1.5 hours. The growth by using the micro-crucible method was realized on fibers from pyrolytic carbon previously treated by thermo-chemical etching to produce welldeveloped surface with micro-crucibles [18]. Results of the growth of CdS whiskers by applying different methods are shown in Fig.…”

“…The ideality factor, η, parametrises how closely charge transmission in a junction follows the ideal Schottky diode. η can be as high as 3.2-9.7 [280] for carbon fiber-CdS heterojunctions whereas η ≈ 1 for conventional solar cells. This comparison indicates that there is large room for improvement of the carbon fiber-SC electronic interface.…”

This review paper summarizes the current state-of-art and challenges for the future developments of fiber-reinforced composites for structural applications with multifunctional capabilities. After a brief analysis of the reasons of the successful incorporation of fiberreinforced composites in many different industrial sectors, the review analyzes three critical factors that will define the future of composites. The first one is the application of novel fiberdeposition and preforming techniques together with innovative liquid moulding strategies, which will be combined by optimization tools based on novel multiscale modelling approaches, so fiber-reinforced composites with optimized properties can be designed and manufactured for each application. In addition, composite applications will be enhanced by the incorporation of multifunctional capabilities. Among them, electrical conductivity, energy storage (structural supercapacitors and batteries) and energy harvesting (piezoelectric and solar energy) seem to be the most promising ones.
