Nanobeam Mechanics: Elasticity, Strength, and Toughness of Nanorods and Nanotubes
The Young's modulus, strength, and toughness of nanostructures are important to proposed applications ranging from nanocomposites to probe microscopy, yet there is little direct knowledge of these
Nanowire Nanosensors for Highly Sensitive and Selective Detection of Biological and Chemical Species
The small size and capability of these semiconductor nanowires for sensitive, label-free, real-time detection of a wide range of chemical and biological species could be exploited in array-based screening and in vivo diagnostics.
Multiplexed electrical detection of cancer markers with nanowire sensor arrays
Highly sensitive, label-free, multiplexed electrical detection of cancer markers using silicon-nanowire field-effect devices in which distinct nanowires and surface receptors are incorporated into arrays opens up substantial possibilities for diagnosis and treatment of cancer and other complex diseases.
Direct ultrasensitive electrical detection of DNA and DNA sequence variations using nanowire nanosensors
Two-terminal silicon nanowire electronic devices that function as ultrasensitive and selective detectors of DNA are reported that show that detection can be carried out to at least the tens of femtomolar range.
Structural ( n, m) determination of isolated single-wall carbon nanotubes by resonant Raman scattering.
It is shown that the Raman scattering technique can give complete structural information for one-dimensional systems, such as carbon nanotubes, by measuring one radial breathing mode frequency omega(RBM) and using the theory of resonant transitions.
Directed assembly of one-dimensional nanostructures into functional networks.
It is shown that nanowires can be assembled into parallel arrays with control of the average separation and, by combining fluidic alignment with surface-patterning techniques, that it is also possible to control periodicity.
Ge/Si nanowire heterostructures as high-performance field-effect transistors
Comparison of the intrinsic switching delay, τ = CV/I, shows that the performance of Ge/Si NWFETs is comparable to similar length carbon nanotube FETs and substantially exceeds the length-dependent scaling of planar silicon MOSFets.
Coaxial silicon nanowires as solar cells and nanoelectronic power sources
These coaxial silicon nanowire photovoltaic elements provide a new nanoscale test bed for studies of photoinduced energy/charge transport and artificial photosynthesis, and might find general usage as elements for powering ultralow-power electronics and diverse nanosystems.
Atomic structure and electronic properties of single-walled carbon nanotubes
Carbon nanotubes are predicted to be metallic or semiconducting depending on their diameter and the helicity of the arrangement of graphitic rings in their walls. Scanning tunnelling microscopy (STM)
Diameter-controlled synthesis of single-crystal silicon nanowires
Monodisperse silicon nanowires were synthesized by exploiting well-defined gold nanoclusters as catalysts for one-dimensional growth via a vapor–liquid–solid mechanism. Transmission electron
