Project Summary


This project was concerned with the controlled growth III-V semiconductor nanowires (NWs) for integration in various device settings and primarily in scanning probe microscopy, exploiting the unique properties of these nanomaterials. For implementation, the project was divided in three workpackages spanning, Nanowire growth & Modelling,  SPM  Fabrication & Applications and Characterisation & Spectroscopy where clear milestones and deliverables were identified for each.  The key objectives of the project summarised below before the core findings are briefly highlighted.


•          Develop nanowire growth protocols to control their physical, optical and energy transport properties at the nanometre scale.

•          Develop theoretical models to provide fundamental insight into the growth mechanisms, characterisation data and to support device integration.

•          Provide clear evidence of a successful integration in devices.

•          Conduct a full characterisation of the nanowires and their growth parameters and that of the devices produced and their operation.  

 

Nanowire growth & Modelling

The potential to achieve controlled growth and the development of theoretical models were investigated. A large amount of growth schemes were carried out and relevant theoretical models and DFT calculation were developed to gain a better insight in the process and to inform on optimal growth conditions to achieve a better control.  The Vapor−Liquid−Solid nanowire (VLS) growth model now widely used in the community and the Vapor–liquid–solid hydride vapour phase epitaxy (HVPE) were proposed. The statistics of nucleation events in NW growing via the VLS mechanism in the mononuclear regime was investigated theoretically. A semi-analytical model was developed to describe the distributions of time intervals between the successive nucleation events and useful characteristics of nucleation statistics. Phase purity was attributed due to a lower surface energy of liquid Ga compare to that of Au-Ga alloys. HVPE nanowire growth only proceeds by introduction of precursors in the catalyst droplets from the vapour phase, promoting almost pure axial growth leading to nanowires with a constant cylinder shape over unusual length. This led to the synthesis of polytypism-free zincblende phase 20 μm long GaAs nanowires exhibiting record radii lower than 15 nm down to 5 nm. The influence of the group V element on the preferred crystal structure of Au-catalyzed III-V nanowires was studied to show that the nanowire elongation rate is limited by the group III transport, while the crystal structure depends on the effective group V to III imbalance. Current-voltage characteristics of (GaMn)As NWs were correlated to growth parameters and theoretical calculations. Theoretical studies of the InAs shell on GaAs NW formation were performed to introduce of the concept of a critical thickness of the external (wetting) layer. Various GaN NWs systems were grown and systematically characterised to describe the relevance of size distribution on the physical properties. Theoretical validation helped establish a scaling thermodynamic model for self-induced nanowires growth rate, leading to the development of a theoretical model of diffusion-induced nanowire growth and self-induced growth. To facilitate the applications of the SPM systems developed, DFT models were developed for various material systems.

 

SPM Fabrication & Applications

The Development of a SPM platform for electrical, optical and thermal properties of nanowires focused on the fabrication of scanning probe microscopy (SPM) tools by integration of nanowires and the creation of their applications platform. A nanofabrication method combining focused ion beam milling and conventional microfabrication techniques was developed to attach carbon nanotubes to SPM tips for thermal and topographical measurements. CNT was shown to exhibit a superior behaviour, leading to topographical and thermal resolution better than 20 and 30 nm, respectively. Thermal transport properties in graphene and high thermal conductivity interconnects materials were carried out. We also tested the use of the bespoke SPM in the liquid environment and conducted nanomechanical and nanothermal SPM measurements. A proprietary technique based on electrochemical sharpening was developed to provide rapid and multiple probes fabrication, higher control of the aspect ratio for the fabrication of ultra-sharp tungsten probes, essential to the manipulation of the nanowires and carbon nanotubes. A method for the formation of single GaAs semiconductor nanowhiskers and their assemblies on the tip of a tungsten needle by molecular-beam epitaxy was developed. Si cantilevers were modified by the direct growth of carbon nanowires to produce nanofork and nanoscalpel structures. Using the modified tips, nanolithography, nanosurgery of erythrocytes and manipulation of colloidal particles with enhanced resolution and precision were successfully demonstrated. We have also demonstrated that it is possible to fabricate electrochemical probes using focused ion beam (FIB) milling where conductive Pt and W tips were grown on the top of processed standard non-conductive SiN AFM probes.

 

Characterisation & Spectroscopy

We focused on the calibration of the SPM tools developed and the characterisation of the physical properties of nanowires, nanowire systems and associated low dimensional nanostructures. Topographical and nanoscale thermal imaging and electrical response measurements were utilised for SPM calibration. Theoretical models were developed to depict modified SPM tips by the integration of nanowires and their operation in various environments. Experimental confirmation data enabled us to extract the fundamental relationship linking nanoscale heat and electronic transport via the nanowire to nanomechanical forces. Finally, we have demonstrated that the SPM analytical platform developed was suitable biomedical applications requiring their operation in liquid environment. The characterisation of the nanowire systems span electronic transport measurements, high resolution microscopy structural analysis, optical properties of individual and various nanowire systems. For instance, (Ga,Mn)As nanowires were grown by molecular beam epitaxy using Mn as a catalyst on GaAs(001) substrates to highlight the effect of an arsenic flux on the growth rate, to determine their electrical characteristics (resistivity and the carrier mobility) and to develop a new model for the determination of the Young's modulus. The current generation in contacted GaAsP nanowire ensembles was used as a novel tool to electrically detect picosecond acoustic pulses. The electrical response is sensitive to the elastic properties of the device and has a frequency cutoff at about 10 GHz. The photovoltaic properties of GaAsP nanowires and core-shell wires contacted using a transparent top contact electrode were investigated to extract electrical and electro-optical properties.  GaN and ZnO nanowires photodetectors were demonstrated using CVD-grown few-layered graphene as a transparent electrode. A theoretical model was developed to describe the photodetector operation. THz generation under excitation by ultrashort optical pulses in ordered arrays of GaAs nanowires was reported, where efficiency of THz radiation generation increases due to the resonant leaky mode excitation in nanowires. Finally, by correlating their concentration, viscosity, electrical properties to their computational response, it was demonstrated that conductive paths in random networks of nanomaterials can be evolved to emulate various functionalities from the same device, i.e. perform computation.

 

In summary, the objectives of the project were delivered. We have made significant contribution to nanowire research and technologies. A comprehensive training programme of early stage researchers was conducted and led to numerous publications, with more than 80 peer-reviewed papers published. Three patents and a spin-out company were reported. Likewise, results from this research contributed to developing new international collaborations and to securing further research funding from national agencies and the European Commission.
