Self-standing chitosan films as dielectrics in organic thin-film transistors
eXPRESS Polymer Letters, 2013 Organic thin film transistors, using self-standing 50 µm thick chitosan films as dielectric, are fabricated using sublimed pentacene or two conjugated polymers deposited by spin coating as semiconductors.

Topological study of the para-line graphs of certain pentacene via topological indices
Open Chemistry, 2018 A topological index is a map from molecular structure to a real number. It is a graph invariant and also used to describe the physio-chemical properties of the molecular structures of certain compounds.

Pentacene Multilayers on Ag(111) Surface [PDF]
The Journal of Physical Chemistry C, 2010 The structural profiles and electronic properties of pentacene (C$_{22}$H$_{14}$) multilayers on Ag(111) surface has been studied within the density functional theory (DFT) framework. We have performed first-principle total energy calculations based on the projector augmented wave (PAW) method to investigate the initial growth patterns of pentacene (Pn)

A simple method to prepare self-assembled organic-organic heterobilayers on metal substrates
AIP Advances, 2011 We demonstrate a self-assembly based simple method to prepare organic-organic heterobilayers on a metal substrate. By either sequential- or co-deposition of para-sexiphenyl (p-6P) and pentacene molecules onto the Cu(110) surface in ultrahigh vacuum, p-6P/

Charge Transport in Pentacene–Graphene Nanojunctions [PDF]
The Journal of Physical Chemistry Letters, 2013 We investigate charge transport in pentacene-graphene nanojunctions employing density functional theory (DFT) electronic structure calculations and the Landauer transport formalism. The results show that the unique electronic properties of graphene strongly influence the transport in the nanojunctions.

Dynamics of Frenkel Excitons in Pentacene [PDF]
Materials, 2018 The dispersion relation for noninteracting excitons and the influence of perturbative corrections are examined in the case of pentacene structure. The values of exchange integrals are determined by nonlinear fits to the experimental dispersion data, obtained by the inelastic electron scattering reported in recent experiments.
