Conversely, both the band mobility and the charge mobility are characterized by oscillations that follow an odd–even trend with a linear decay for increasing number of the carbon atoms. Specifically, the threshold voltage, contact resistance and temperature-dependent constant exhibit parabolic trends for increasing alkanethiol chain length. It can also be easily scripted (the saved le formats are similar to Python scripts) or used as module inside Python.

The program features a graphical user interface (GUI), which works under Unix/Linux, Windows or Mac OS. It is designed to be easy to use, easily extensible, but powerful. In particular, the thickness dependence of both the charge mobility and the charge carrier accumulation can be explained in terms of the molecular order at the interface between the pentacene films and the SAMs. Veusz is a 2D and 3D scientic plotting package. Use the trendline for the log-transformed data as a power for : This is the exponential model. : Get a (linear) trendline for the log-transformed data: The trendline is. Measuring the current flowing into the channel allows us to establish a correlation between the charge injection and the pentacene film growth. To carry out the log-transform fitting: Make a table in Excel which contains the data we want to fit, and also the log-transformed data: Plot the log-transformed data. The source and drain electrodes are made of gold functionalized with alkanethiol Self-Assembled Monolayers (SAMs), whose number of carbon atoms ranges from 5 to 10. Charge injection in Organic Field Effect Transistors is investigated by monitoring in real-time the electrical conduction, while in situ growing pentacene films.
