Polarization-induced transport in ferroelelctric organic field-effect transistors
(University of Missouri--Columbia, 2019)
In this research we study the role of ferroelectric dielectrics in organic field-effect transistors (FETs) to understand the mechanism of charge transport in organic semiconductors. The ferroelectric nature of the polymer, ...
The use of ferroelectrics and dipeptides as insulators in organic field-effect transistor devices
(University of Missouri--Columbia, 2016)
While the electrical transport characteristics of organic electronic devices are generally inferior to their inorganic counterparts, organic materials offer many advantages over inorganics. The materials used in organic ...
Exploring polymer dielectrics for donor-acceptor and small molecule based transistors and voltage inverters
(University of Missouri--Columbia, 2023)
Organic semiconductor devices have gained much attention over the past several decades. Solution processability of polymer materials lends itself towards the realization of flexible, wearable electronic devices, owing to ...
Donor-acceptor copolymers and sol-gel processable zinc oxide for thin film transistors and hybrid photodetectors
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Organic semiconductors have been gaining attention both in research and commercial development for electronic devices due to their low manufacturing ...
Charge-transfer and other excitonic state in conjugated polymer : fullerene blends-implication in photovoltaics
(University of Missouri--Columbia, 2014)
Over the last few decades there has been tremendous progress in organic photovoltaics (OPVs), with efficiencies reaching over 10%. Still, many factors including the origin and the dynamics of charge carrier involved are ...
Raman scattering studies and charge transport in polyfluorenes
(University of Missouri--Columbia, 2007)
Blue-emitting polyfluorenes (PFs) have emerged as especially attractive [pi] conjugated polymers (CP) due to their strong blue emission and excellent electronic properties and thus great prospects for device applications. ...
High pressure spectroscopic studies of organic device materials
(University of Missouri--Columbia, 2012)
A comparison of photoluminescence spectra of as-is and thermally cycled di-octyl substituted polyfluorene (PF8) under pressure has been used to disentangle inter- and intra-chain interactions. Raman study of this system ...
Low dielectric constant-based organic field-effect transistors and metal-insulator-semiconductor capacitors
(University of Missouri--Columbia, 2012)
This thesis describes a study of PFB and pentacene-based organic field-effect transistors (OFET) and metal-insulator-semiconductor (MIS) capacitors with low dielectric constant poly(methyl methacrylate) (PMMA), poly(4-vinyl ...
Light scattering studies of organic field effect transistors
(University of Missouri--Columbia, 2013)
Organic semiconductors hold a great promise of enabling new technology based on low cost and flexible electronic devices. While much work has been done in the field of organic semiconductors, the field is still quite ...
