Article Title: Selective activation of hydrogen passivated silicon and germanium surfaces
Article Snippet: Conductivity (shown as S(Siemens)/cm on the vertical axis) is generally measured with a four-point probe.

Article Title: Electrochemical-codeposition methods for forming carbon nanotube reinforced metal composites
Article Snippet: FIG. 4 shows the electrical conductivity (×106 Siemens) measured with a four-point probe at room temperature on fabricated Cu/SWNT nanocomposite according to a disclosed embodiment and electrochemically deposited copper.

Article Title: Synthesis of liquid crystal polymers containing cholesterol side groups and investigation of their usability potential as an insulator in organic field effect transistor (OFET) applications
Article Snippet: Cholesterol bearing side chain liquid crystal polymers (SCLCP) were prepared and the chemical structures of these polymers were determinated by Fourier Transform Infrared (FTIR), 1H Nuclear Magnetic Resonance Spectroscopy (1H NMR), and Gel Permeation Chromatography (GPC).. Mesogenic properties of the polymers were examined by Wideand Small-angle X-ray Scattering (WAXS and SAXS), Thermogravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC) and Polarising Optical Microscopy (POM).. The results revealed that all polymers have broken focal conic textures of the smectic liquid crystals, encouraging the mesomorphism.

Article Title: Process to form highly conductive feature from silver nanoparticles with reduced processing temperature
Article Snippet: As disclosed herein, the term “highly conductive feature” refers to a conductive feature having an electrical conductivity of at least about 0.1 Siemens/centimeter (“S/cm”), at least about 100 S/cm, at least about 500 S/cm, at least about 1,000 S/cm, at least about 5,000 S/cm, at least about 10,000 S/cm, or at least about 20,000 S/cm as measured by, e.g., four-point probe method.

Article Title: Multi-layer radiation detector
Article Snippet: In one instance, the conductivity (determined with a four-point measurement) was 100 Scm−1 (Siemens per centimeter), resulting in a resistance of 33 milliohm (mOhm) for a 30 μm thick adhesive of 300 μm×300 μm cross section.

Article Title: Composite materials with high Z-direction electrical conductivity
Article Snippet: In some embodiments, the cured composite material containing the combination of conductive nano-particles and carbon veil but no polymeric particles at the interlaminar region, has the following properties: electrical conductivity in the z-direction of at least about 10 S/m (Siemens per meter), for example, from about 10 S/m to about 100 S/m, as measured in DC conditions according to a 4-probe testing method, CAI at 270 in-lbs (or 30.5 J) of at least about 25 Ksi, for example, from about 25 Ksi (or about 172 MPa) to about 45 Ksi (or about 310 MPa), as measured in accordance with ASTM-D7137 and interlaminar fracture toughness under mode I (GIc) of at least about 1.2 in-lb/in2, for example, from about 1.2 in-lb/in2 (or about 210 J/m2) to about 3 in-lb/in2 (or about 522 J/m2), as measured in accordance to ASTM-D5528.

Article Title: Silver nanoparticle process
Article Snippet: The conductivity of the resulting silver-containing element produced by heating the deposited silver-containing nanoparticle composition is for example more than about 0.1 Siemens/centimeter (“S/cm”), more than about 100 S/cm, more than about 500 S/cm, more than about 2,000 S/cm, more than about 5,000 S/cm, more than about 10,000 S/cm, and more than about 20,000 S/cm as measured by four-probe method.
