Material characterisation of nanowires with intrinsic stress
(2017)When fabricating nanowires in a doubly-clamped beam configuration it is possible for a residual axial stress to be generated. Here, we show that material characterisation of metal and semiconductor nanowires subjected ... -
"Quantitative study of the photothermal properties of metallic nanowire networks"
(2015)In this article, we present a comprehensive investigation of the photothermal properties of plasmonic nanowire networks. We measure the local steady-state temperature increase, heat source density, and absorption in Ag, ... -
Effective medium theory for the conductivity of disordered metallic nanowire networks
(2016)Motivated by numerous technological applications, there is current interest in the study of the conductive properties of networks made of randomly dispersed nanowires. The sheet resistance of such networks is normally ... -
Solvent-Engineered Stress in Nanoscale Materials?
(2018)Nanoscale materials are frequently coated with surface stabilisation layers during growth that prevent flocculation in solution and facilitate processing technologies such ink-jet device printing. Here, we show that ... -
Metal Nanostructure Synthesis via Surface Energy Driven Growth
(2016)Identifying new synthesis methods to produce single crystal metal nanowires has the potential to expand nanowire based technology integration and increase applications. The catalogue of single crystal metal nanostructures ... -
Co-percolation to tune conductive behaviour in dynamical metallic nanowire networks
(2016)Nanowire networks act as self‐healing smart materials, whose sheet resistance can be tuned via an externally applied voltage stimulus. This memristive response occurs due to modification of junction resistances to form a ... -
Associative Enhancement of Time Correlated Response to Heterogeneous Stimuli in a Neuromorphic Nanowire Device
(2016)In spite of the strong interest in brain‐like or neuromorphic computation, relatively few devices have emerged whose neuromorphic behavior is embedded in the hardware itself and not reliant on external programming of ... -
Position Controlled Growth of Single Crystal Cu3Si Nanostructures
(2015)In this work we demonstrate the position controlled growth of single Cu3Si nanostructures using a Ge-Cu bilayer film that contains a pattern of defects on a Si substrate with a thin oxide layer. The defects act as nucleation ... -
