Temperature dependence of contact resistance for gold-graphene contacts
2017 47th European Solid-State Device Research Conference (ESSDERC), 2017We report temperature dependent transport properties of back-gated graphene TLM structures in a wide temperature range from 35 K to 450 K. We use gold as the contact material and find that the contact resistance exhibits a strong temperature dependence, dropping considerably to a value of 315±127 Ωμm at 35 K as compared to 957±210 Ωμm at 450 K measured

This contribution aims at analyzing one case of resistance to interference, with the ultimate goal of contributing to a predictive theory of the conditions on contact-induced language change. This paper explores the possibility that interference is necessarily the result of structural reanalysis of strings of E-language already weakly generated in the ...

A Silicon - Metal Contact Resistance
Nature, 1947The rectifying action of a silicon crystal valve is a property of the contact between the silicon and a metal ‘cat's-whisker’. In order to complete the circuit it is necessary to have a second silicon – metal contact the resistance of which must be small compared with that of the rectifying contact, so that the rectifying action is not cancelled out by

Thermal Spreading Resistance in Multilayered Contacts: Applications in Thermal Contact Resistance
Journal of Thermophysics and Heat Transfer, 1999Application of highly conductive coatings to contacting surfaces is a commonly employed method to enhance thermal contact conductance. In many applications it is often necessary to apply an intermediate coating such that the conductive coating may be applied to a nonadhering substrate.

Determining specific contact resistivity from contact end resistance measurements
IEEE Electron Device Letters, 1984A method is described to determine specific contact resistivity from contact end resistance measurements using a transmission line model. A test pattern is described which minimizes the effect of current fringing around contact corners and yields an accurate determination of contact width.

Novel method to determine contact resistivity and sheet resistance under the contact
International Journal of Electronics, 1999A method to determine specific contact resistance and sheet resistivity under the contact using two L-type cross Kelvin resistors is presented. In the model analysed in the present paper, the sheet resistivity under the contact was different from the resistance of the layer outside the contact.

Measurement of contact resistance of an ohmic contact applied to a high resistivity photoconductor
Review of Scientific Instruments, 1981A technique is described to estimate the contact resistance of an ohmic contact, under dynamic conditions, applied to a high resistivity photoconductor. It has been used to estimate the contact resistance of an ohmic contact (Au–Ge) applied to a semiinsulating Cr-doped GaAs (p≊108 W cm).

Measurement of Contact Resistance
Review of Scientific Instruments, 1967An instrument for measuring the long term quality of electrical connecting devices is described. The parameter which controls this property is the contact resistance. In the instrument described, the contact and bulk resistance are separated by utilizing the difference in thermal response time between a contact spot and bulk metal.

Friction and Contact Resistance through True Contact Interface
IEICE Transactions on Electronics, 2006The main factor determining for both friction and contact resistance is the true contact area in the contact interface. Contact resistance depends on the size of the true contact area and contaminant films interposed between the contact areas of the interface. Moreover, friction force also depends on the true contact area.

Effect of space angle on constriction resistance and contact resistance for a point contact
Journal of Applied Physics, 1985It can generally be considered that an actual contact makes an angle with the extension of the contact surface because the tip of a contact element is convex in shape (macroscopically) and has surface roughness (microscopically). The effect of this angle on constriction resistance and contact resistance for a point contact is analyzed theoretically by ...
