“…Pentacene films deposited from the vapour phase have been provided by conventional thermal deposition, cluster beam deposition [23], pulsed laser deposition [24], molecular beam deposition in ultra-high vacuum [8] and physical vapour deposition (PVD) in a low vacuum [18]. Conventional thermal deposition is used for pentacene film deposition in many cases.…”

“…Chemicals used for surface treatment of gate dielectrics are shown in figure 9. The chemicals are classified into (1) trichlorosilane (9)(10)(11)(12)(13)(14)(15)(16)(17)(18) [83,90,91], (2) alkoxysilane (19-21) [92], (3) phosphonic acid (22) [14,93] and (4) silazane (23) [94] according to the reaction group. Some of the chemicals have been used to obtain self-assembled monolayer (SAM).…”

“…This implies that the thickness of the organic layer formed by surface treatment influences mobility. On the other hand, hexamethyldisilazane (HMDS) (23) was effective for high mobility though the layer is much thinner than for 9 and 10.…”

“…We demonstrated low-voltage-operating high-performance pentacene TFTs using a bilayer consisting of a thick Ti 0.17 Si 0.83 O 2 layer and a thin SiO 2 layer [98]. The surface of the SiO 2 layer was treated by HMDS (23). The mixed metal oxide Ti 0.17 Si 0.83 O 2 had a flat surface comparable to thermal silicon oxide and the flatness contributed to the high field-effect mobility.…”

Organic field-effect transistors (FETs) have attracted considerable attention because of their potential for realizing large-area, mechanically flexible, lightweight and low-cost devices. Pentacene, which is a promising material for organic FETs, has been intensely studied. This article reviews the basic properties of pentacene films and crystals, and the characteristics of pentacene FETs fabricated under various conditions, including our recent achievement of low-voltage operating high-mobility FETs. The basic properties include the crystal polymorph, the band structure and the effective mass. These data have been used for discussion of carrier transport and mobility in pentacene films. The characteristics of pentacene FETs generally depend on the conditions of the pentacene film and the gate-dielectric surface. The dependences are summarized in the article. In addition, liquid-crystal displays and organic light-emitting device arrays using pentacene FETs are reviewed as applications of organic FETs, and complementary metal–oxide–semiconductor circuits using our low-voltage operating FETs are also shown.

“…Pentacene and its derivatives have a number of applications in the development of organic thin-film transistors, organic NLO materials, solar cells, organic light-emitting diodes (OLEDs), etc. many studies have presented wide usage of Pentacene in the field of photovoltaics [11][12][13][14]. Due to having high mobility, the derivatives of Pentacene are also used as p-type organic semiconductors [15].…”

The present study deals with the investigation of the change in the hyperpolarizability of Pentacene-2,5-dione (PD) on the introduction of the gold (Au) and silver (Ag) nanoclusters using the density functional theory (DFT). The involvement of the nanoclusters induces the intramolecular interactions, which is confirmed by the electrostatic potential plot and Mulliken charge distribution. The process of adsorption of metal clusters on the surface of PD is investigated by absorption spectra and the Raman spectra analysis. The global reactivity parameters validate a hike in the reactivity of the PD after the adsorption of Ag3 and Au3 nanoclusters. The study reported extraordinary enhancement in the hyperpolarizability of the metal nanoclusters adsorbed complexes. The high value of hyperpolarizability for PD-Ag3 (184.22×10 -30 esu) and PD-Au3 (2057.26×10 -30 esu) validates their applications in highly efficient NLO devices. The statistical calculation of radiative lifetime and light-harvesting efficiency reveals that probe PD can fruitfully contribute to the development of photo luminescent material and photosensitizer dye in dye synthesized solar cells.
