Journal ArticleDOI
Charge Trapping in Intergrain Regions of Pentacene Thin Film Transistors
TL;DR: In this paper, a scanning Kelvin probe microscopy (SKPM) study of the surface potential of vacuum sublimed pentacene transistors under bias stress and its correlation with the film morphology is presented.
Journal ArticleDOI
High-Mobility Aligned Pentacene Films Grown by Zone-Casting
Claudia M. Duffy,Jens Wenzel Andreasen,Dag W. Breiby,M. Nielsen,Masahiko Ando,Takashi Minakata,Henning Sirringhaus +6 more
TL;DR: In this paper, the growth and field-effect transistor performance of aligned pentacene thin films deposited by zone-casting from a solution of unsubstituted Pentacene molecules in a chlorinated solvent was investigated.
Journal ArticleDOI
A scanning Kelvin probe study of charge trapping in zone-cast pentacene thin film transistors.
TL;DR: It is concluded that oxygen is able to penetrate and disassociatively incorporate into crystalline pentacene, chemically creating electrically active defect states.
Journal ArticleDOI
Evidence for Charge‐Trapping Inducing Polymorphic Structural‐Phase Transition in Pentacene
Masahiko Ando,Tom B. Kehoe,Makoto Yoneya,Hiroyuki Ishii,Kawasaki Masahiro,Claudia M. Duffy,Takashi Minakata,Richard T. Phillips,Henning Sirringhaus +8 more
TL;DR: Trapped-charge-induced transformation of pentacene polymorphs is observed by using in situ Raman spectroscopy and molecular dynamics simulations reveal that the charge should be localized in pentacenes molecules at the interface with static intermolecular disorder along the long axis.
Journal ArticleDOI
Disorder and localization dynamics in polymorphs of the molecular semiconductor pentacene probed by in situ micro-Raman spectroscopy and molecular dynamics simulations
Masahiko Ando,Makoto Yoneya,Thomas B. Kehoe,Hiroyuki Ishii,Takashi Minakata,Kawasaki Masahiro,Claudia M. Duffy,Richard T. Phillips,Henning Sirringhaus +8 more
TL;DR: In this article, the electrical properties of field-effect transistors with zone-cast pentacene films were characterized by using in situ micro-Raman spectroscopy to monitor the films' intermolecular and intramolecular vibrations.
