(Fig.1b). Second, additional Se is added to further introduce the Cu vacancies and reduce the bond energy in the material. Tuning the Cu content can regulate the hole concentration and the temperature of the phase transition, then the highly enhanced average power factor (PFave.) is ...
method on a ZEM-3 electric resistance measurement system at room temperature. Because the length according to ASTM standard (300 mm) is far beyond the currently available L-PBF machine’s capacity to build, the non-standard length was used56. The volume resistivity can be calculated as ...
found by considering an ambient temperature of 20 °C. However, all these loss contributions are temperature-dependent, especially the ohmic losses. In fact, the electrical resistivity of conductors changes linearly with temperature. It was therefore expected that, when the steady-state temperature ...
Here we present the influence of cyclic vibrations and temperature on the electrical properties of thin copper films bonded to FR4. A custom-made four-probe head was used to measure voltage and determine different electrical parameters such as sheet resistance, resistivity, and electrical conductivity...
The softness of copper partly explains its high electrical conductivity (59.6×106 S/m) and high thermal conductivity, second highest (second only to silver) among pure metals at room temperature.[12] This is because the resistivity to electron transport in metals at room temperature originates ...
[158] reported high electrical resistivity with values ~0.5–500 Ω cm in RCuX2 (R=Gd, Dy, Er) which are larger than the typical high-performance thermoelectric materials by 2–5 orders of magnitude. The thermoelectric performance can be further enhanced by doping at the R site in ...
