Calculation of DOS-Dependent Channel Potentials in FETs in the Saturation Condition
Woo-young So, David V. Lang, Arthur P. Ramirez
We calculated functions for the potential, Vch, in the channel of a field effect transistor with various densities of the localized states (DOS) by using a device simulator. In the…
Dependence of Mobility on Density of Gap States in Organics by GAMEaS - Gate Modulated Activation Energy Spectroscopy
W. So, D. V. Lang, V. Y. Butko +3
We develop a broadly applicable transport-based technique, GAte Modulated activation Energy Spectroscopy (GAMEaS), for determining the density of states (DOS) in the energy gap. GA…
Amorphous-like Density of Gap States in Single Crystal Pentacene
D. V. Lang, X. Chi, T. Siegrist +2
We show that optical and electrical measurements on pentacene single crystals can be used to extract the density of states in the HOMO-LUMO bandgap. It is found that these highly p…
Limit of Field Effect Mobility on Pentacene Single Crystal
V. Y. Butko, X. Chi, D. V. Lang +1
We report on fabrication and characterization of field effect transistors (FETs) on single-crystal pentacene. These FETs exhibit hole conductivity with room temperature effective m…
