contact resistance उदाहरण वाक्य

Second, contact resistance between each layer in the device should be minimized to offer higher fill factor and power conversion efficiency.
Also, due to the semiconducting nature of the CNT, a Schottky barrier forms at the metal-semiconductor interface, increasing the contact resistance.
To return a used probe card to a contact resistance that is acceptable the probe tips need to be thoroughly cleaned.
You will find that the contact resistance between the battery or other source and the wire will greatly increase this resistance.
In the four-probe case, there is no potential drop across the voltage measurement leads so the contact resistance drop is not included.

At the beginning of the weld, the contact resistances are usually high, so most of the initial energy will be dissipated there.
However, in doing so, it will protect the primary contact from arcing, so a low contact resistance will be established a millisecond later.
This is because the meter's reading is the sum of the resistance of the measuring leads, the contact resistances and the resistance being measured.
Contact resistance causes power dissipation via Joule heating in low frequency and analog circuits ( for example, solar cells ) made from less common semiconductors.
The slope of the linear function is related to the channel transconductance and can be used for estimation of the contact resistance-free carrier mobility.
