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

CONTACT PROBE FOR CORNEAL TEMPERATURE MEASUREMENTS
Acta Ophthalmologica, 1975A thermistor probe for corneal temperature measurements is presented. The temperature‐sensing cartridge is similar in shape to an electronic tonometer, and the procedure of corneal temperature registration is performed just as easily and in a similar manner as for tonography.

Cryogenics, 2012
Abstract The microscopic heat transfer between solid and solid at cryogenic temperatures exists in many application fields. This paper employed the Laser Photothermal Method (LPM) which is a transient and non-contact method to measure the Thermal Contact Resistance (TCR) between solid and solid in the temperature range of 70–290 K and the pressure ...

The temperature-dependence of the dynamic contact angle
Journal of Colloid and Interface Science, 2019The wetting of a solid by a liquid is a thermally-activated molecular rate process, which may be investigated by studying the temperature-dependence of the dynamic contact angle at standard experimental scales.We use the plunging-tape method and a low-powered microscope to measure the dynamic contact angle of di-n-butyl phthalate (DBP) on poly(ethylene

Contact probe for skin temperature measurements
Journal of Physics E: Scientific Instruments, 1972A contact probe to accurately measure skin temperature under clinical conditions has been developed and tested. The most important characteristic of this probe is that the time required for the skin to return to its normal condition after having been disturbed by the initial contact with the probe is only about 20 seconds.

Contact temperatures in mixed friction
Tribology International, 1971Abstract An infra-red technique for measuring the contact temperature in mixed friction is described. It can detect temperatures as low as 30°C above ambient. The shape of curves comparing the variation of the coefficient of friction, and the contact temperature with time are similar.

Thermal contact conductance of pressed contacts at low temperatures
Cryogenics, 2004Abstract The influence of variations of interface temperature in the range 50–300 K on the thermal contact conductance between aluminium and stainless steel joints was determined. Predictions were done by modeling the deformation at the interface for different values of surface finish and contact pressure over the range of interface temperatures ...

Contact Temperature and Its Effects in an Oscillatory Sliding Contact
Journal of Tribology, 1989The relationship between contact temperature, friction coefficient, and wear rate was studied here for the case of dry sliding between pin and flat in small amplitude oscillatory motion. In the first part of the study, infrared radiation pyrometry and finite element analysis techniques were used to measure and model surface temperatures in an ...

Non-contact temperature measurement
NDT & E International, 1991Three methods for noncontact temperature measurement are presented. Ideal gas thermometry is realized by using laser-induced fluorescence to measure the concentration of mercury atoms in a Hg-Ar mixture in the vicinity of hot specimens. Emission polarimetry is investigated by measuring the spatially resolved intensities of polarized light from a hot ...

Critical temperatures of contact materials
IEEE Transactions on Components, Hybrids, and Manufacturing Technology, 1992The influence of cathode temperatures on the dielectric strength of contact materials is investigated in the temperature region between 300 and 1600 K. Experimental results show that contact materials investigated in this paper have certain critical temperatures. Below the critical temperatures, the dielectric strengths of the materials are equal to or
