发帖数: 578 | 1 Since conducting polymer has similiar conductivity as copper, so I assume its
hole mobility is at same order as electron mobility in metal. Is it right?
thanks. Who studying this pls give some hints. thanks. |

Which polymer?
In my memory, most are not. Much much smaller, even with the same conductivity.

I think hole mobility in polymer should be related to its conductivity. Why it
is much smaller? I got some data for the hole mobility. The largest is 0.1 ~ 1
cm2/Vs for field effect hole mobility, reponsding to 10 cm2/Vs for defect free
hole mobility.
I am quite confused at all those concepts such as hole drift velocity,
field-effect hole mobility and defect free hole mobility.
I am checking some book talking about them. But still prefer some book
especially talking abou

发帖数: 82 | 4 I don't know either. But keep two fact in mind:
1. conductivity is not only the function of mobility, but that of carrier
density.
2. The charge carriers in polymer are not free carrier. Some are polarons, some
are solitons.

charge carrier.
The neutral form of CP is the semiconductor. In the case of CP, I think
poly(3-alkylthiophene) has the highest hole mobility.

You are right at the polymer which has the highest hole mobility.
FYI, there is another type polymer called instinc conducting polymer that
doesn't require dopant.
