Silver Nanowire Networks as Flexible, Transparent, Conducting Films: Extremely High DC to Optical Conductivity Ratios
(2009)
We have used aqueous dispersions of silver nanowires to prepare thin, flexible, transparent, conducting films. The nanowires are of length and diameter close to 6.5 ?m and 85 nm respectively. At low thickness, the films ...
Synthesis, electrical and magnetotransport properties of polypyrrole-MWCNT nanocomposite
(2012)
The present work describes the preparation of nanocomposites in which the multiwall carbon nanotubes (MWCNT) have been mixed with conducting polypyrrole (PPy) via an in situ chemical oxidative preparation method. To reveal ...
Physical Mechanism for the mechanical reinforcement in nanotube-polymer composite materials
(2005)
The significant increase in the Young?s modulus of nanotube-polymer composites is often correlated with the formation of a crystalline layer of polymers surrounding the nanotubes. Although the improved stress transfer ...
Evolution of resistive switching over bias duration of single Ag2S nanowires
(2010)
We report experimental results of ultralow frequency photocurrent oscillation in individual ZnO
nanowires. Consecutive photocurrent and photoluminescence measurements corroborate the process
of capture and release of ...
Size selective photoluminescence excitation spectroscopy in CdTe quantum dots
(2003)
We present a photoluminescence and photoluminescence excitation study of CdTe quantum dots,
prepared via a novel organometallic approach. The global photoluminescence (excited at the energy
above the absorption edge) ...
Laser triggered Z-pinch broadband extreme ultraviolet source for metrology
(2013)
We compare the extreme ultraviolet emission characteristics of tin and galinstan (atomic %:
Ga: 78.35, In: 14.93, Sn: 6.72) between 10 nm and 18 nm in a laser-triggered discharge between
liquid metal-coated electrodes. ...
Stability maps for columnar structures
(2023)
We have previously explored the hysteresis and reversibility of transitions between ordered packings of soft spheres of diameter d in cylindrical channels of diameter D [A. Mughal, J. Winkelmann, D. Weaire, S. Hutzler, ...
Molecular electronics: first principles and model approaches
(Trinity College (Dublin, Ireland). School of Physics, 2015)
This thesis deals with the application and the development of computational tools for the study of ground state and electronic transport properties of molecular junctions. The calculations can be divided in two main ...
Emission Properties of Colloidal Quantum Dots on Polyelectrolyte Multilayers
(2006)
We present steady state and time-resolved photoluminescence (PL) characteristics of differently charged CdTe quantum dots (QDs) adsorbed onto a polyelectrolyte (PE) multilayer. The PE multilayer is built up using a ...
Supramolecular approaches to metal-organic gels using 'Chevrel-type' coordination clusters as building units
(2013)
A novel hexanuclear {Mn6} coordination complex with octahedral topology has been prepared and was subsequently used as a building unit for the construction of coordination polymers and metal?organic gels; the latter exhibit ...
