However, the sun-light transmittance of the TCP layer and the contact resistance of the TCP and the TCO need to be optimized.
where [R.sub.c] is the contact resistance of the wire/copper tape with pencil graphite for one electrode; [R.sub.g] is the resistance of the graphite resistor.
However, high contact resistance between CNTs and drain/source metal electrodes limits the performance of CNT-FETs due to different work function.
A supplier's manufacturing error omitted required welds from electrical contact pins within the unit, potentially leading to a gradual increase in contact resistance over time.
The contact resistance is typically 20 milliohms per pin.
As devices become smaller, increased contact resistance for carbon nanotubes has hindered performance gains until now.
Knowing the [DELTA]S value at each position for each Brush-segment contact, the aim is to build the equivalent contact resistance. Some authors use a conductance model proportional to the [DELTA]S value [17, 18].
Among the five notable trends: 1) Lower contact resistance. Contact resistance has a negative impact on current carrying capability and leads to higher socket operating temperatures.
The CNT/PTFE composite film was characterized on the electrical conductivity, the contact resistance between the bipolar plate and carbon paper, the contact angle of water, and the polarization curve.
