“…This technique mainly contains ejected drop printing, contact stamp printing, indirect and offset printing methods, and capillary stylus dispensing. The comparison of these techniques in terms of advantages and disadvantages has been reported by some comprehensive reviews [55,56]. Among them, piezo inkjet printing has dominated OFET fabrication printing techniques due to its excellent compatibility and the availability of sophisticated print heads to the development community.…”

“…Since charge carriers are preferentially transported along the π-π stacking direction in organic semiconductors, macroscopically aligned organic films have potentially higher mobilities and provide more unusual properties, such as optically and electrically anisotropic characteristics. Therefore, many deposition techniques have been investigated for patterning and alignment of organic semiconductors [56]. The techniques mainly contain (1) mechanical forces alignment, such as friction-transfer, nanoimprinting, and the Langmuir-Blodgett (LB) technique; (2) depositing the organic semiconductors directly on the alignment layers prepared by different methods, such as rubbing and photoirradiation; (3) growing the organic semiconductors on inorganic single crystals; (4) using magnetic or electric field-induced alignment; (5) using solution-processed technique to align organic semiconductors on isotropic substrates.…”

Organic field-effect transistors have received much attention in the area of low cost, large area, flexible, and printable electronic devices. Lots of efforts have been devoted to achieve comparable device performance with high charge carrier mobility and good air stability. Meanwhile, in order to reduce the fabrication costs, simple fabrication conditions such as the printing techniques have been frequently used. Apart from device optimization, developing novel organic semiconductor materials and using thin-film alignment techniques are other ways to achieve high-performance devices and functional device applications. It is expected that by combining proper organic semiconductor materials and appropriate fabrication techniques, high-performance devices for various applications could be obtained. In this chapter, the organic field-effect transistor in terms of device physics, organic materials, device process, and various thin-film alignment techniques will be discussed.

Naphthalocyanine (Nc) thin films have been grown by sublimation on SiO2. We have used atomic force microscopy and X-ray diffraction to show that the films are disordered for room temperature deposition, but show a highly crystalline needle-like morphology for a substrate temperature of ~200 o C. Field effect transistors exhibit p-channel operation with a mobility, which has a peak value of 0.052 cm 2 /Vs, showing a high dependence on substrate temperature. Exposure to atmosphere results in an increase in current and mobility and a reduction in threshold voltage. We compare our results with films formed from analogue molecules such as phthalocyanines and naphthalocyanine functionalised with solubilising sidegroups and discuss the potential of Nc for applications in organic electronics and sensors.

AGRADECIMENTOSAgradeço ao professor Henrique Eisi Toma pelas inúmeras oportunidades, começando pela de me receber no seu laboratório sob sua orientação, passando pelas instruções e inspirações, e acabando na confiança para poder me desenvolver profissionalmente. Sempre muito obrigado.Agradeço ao professor Koiti Araki pelas muitas ocasiões em que fora como um segundo orientador, sempre prestes também a me fornecer valiosíssimas dicas e partilha de conhecimentos, pela confiança e amizade.Aos professores membros da banca pela disponibilidade para revisar esta tese e as importantes contribuições.Um agradecimento muito especial ao professor Alberto Bolaños Rivera com quem aprendera as primeiras noções da química de coordenação e da vida científica quando me orientou na graduação. A refined study of films derived from vanadium pentoxide gel was carried out based on spectroscopic and microscopic techniques, aiming a better understanding of this material on a microscopic scale. It was demonstrated that the vanadium pentoxide gel consists of a suspension of anisotropic nanoparticles which remains stable even at high concentrations. The structural and spectroscopic properties of such nanoparticles were reviewed and discussed, providing new insights at the state of the art. It was also investigated the occurrence of some relevant phenomena, such as the laser induced phase transition, and to develop new technological applications in areas such as gas sensing and lithography. The collection of results described in thesis highlighted a great research potential of confocal Raman microscopy, in the field of nanomaterials.
