Ultrafast carrier dynamics in band edge and broad deep defect emission ZnSe nanowires
(2007)
Ultrafast carrier dynamics of ZnSe nanowires grown under different growth conditions have been studied. Transient absorption measurements reveal the dependence of the competing effects of state filling and photoinduced ...
Long-range charge transport in single G-quadruplex DNA molecules
(2014)
DNA and DNA-based polymers are of interest in molecular electronics because of their versatile and programmable structures. However, transport measurements have produced a range of seemingly contradictory results due to ...
Ultrafast time-resolved spectroscopy of ZnSe nanowires: Carrier dynamics of defect-related states
(2009)
In recent years, ZnSe nanowires have been widely investigated for their potential applications in optoelectronics. A typical room temperature photoluminescence spectrum of ZnSe nanowires grown by vapor-liquid-solid growth ...
An investigation into the conversion of In2O3 into InN nanowires
(2011)
Straight In2O3 nanowires (NWs) with diameters of 50 nm and lengths ≥2 μm have been grown on Si(001) via the wet oxidation of In at 850°C using Au as a catalyst. These exhibited clear peaks in the X-ray diffraction corresponding ...
Optical response of II-VI ZnSe nanowires

Extracellular appendages of the dissimilatory metal-reducing bacterium Shewanella oneidensis MR-1 were recently shown to sustain currents of 10 10 electrons per second over distances of 0.5 microns [El-Naggar et al., Proc. ...
Ultrafast hole carrier relaxation dynamics in p-type CuO nanowires
(2011)
Ultrafast hole carrier relaxation dynamics in CuO nanowires have been investigated using transient absorption spectroscopy. Following femtosecond pulse excitation in a non-collinear pump-probe configuration, a combination ...
Review: Probing protein electron transfer mechanisms from the molecular to the cellular length scales
(2013)
The mechanisms of bridge-mediated electron transfer (ET) reactions vary from coherent deep tunneling to thermally activated hopping. This short review focuses on some developments in the study of protein ET mechanisms at ...
High yield-low temperature growth of indium sulphide nanowires via chemical vapor deposition
(2010)
Indium sulphide nanowires (NWs) have been grown on Si via the reaction of In and InCl3 with H2S using chemical vapor deposition at temperatures as low as 250 °C. We find that the growth of InxSy NWs via the direct reaction ...
