“…2,3 Research on OPBTs covers experimental techniques and methods for improving the performance of n-type as well as p-type OPBTs. [2][3][4][5][6][7][8][9][10][11][12][13][14] Klinger et al recently showed easy-to-produce OPBTs based on the n-type semiconductor C 60 , reaching high current densities above 10 A/cm 2 and transit frequencies in the MHz-regime at low voltage. 8 The devices are fabricated by a layer by layer vacuum deposition, and after processing of the base electrode, the device is exposed to air for several minutes, leading to a thin native aluminum oxide film around the base electrode.…”

“…A tecnologia de exibição nĂŁo Ă©, entretanto, o Ășnico campo em que materiais orgĂąnicos em geral, e polimĂ©ricos conjugados em particular, aparecem com um futuro promissor. Entre esses novos campos aparecem as novas tecnologias de cĂ©lulas solares [5][6][7][8] , transistores [9][10][11] , emissores tipo laser, sistemas de armazenamento e circuitos integrados polimĂ©ricos [12][13][14][15][16][17] . O uso de materiais orgĂąnicos, polimĂ©ricos ou nĂŁo, nos vĂĄrios tipos de dispositivos tem, entre suas principais vantagens, a imensa possibilidade de preparação de estruturas quĂ­micas diferentes, alĂ©m de poderem ser misturados, formando sistemas com outras propriedades.…”

“…Entretanto, os polĂ­meros eletroluminescentes apresentam um problema muito comum que Ă© a baixa solubilidade, decorrente do tipo de estrutura quĂ­mica, o que cria dificuldades para preparação dos filmes finos polimĂ©ricos e de espessura uniforme, por quaisquer das tĂ©cnicas usualmente empregadas (deposição por espalhamento centrĂ­fugo de soluçÔes, deposição por jato de tinta, formação de filmes por Langmuir-Blodgett (LB) e por auto-montagem 9,10,18,22,23,84 ). Para aumentar a solubilidade dos polĂ­meros conjugados, a estratĂ©gia normalmente utilizada Ă© a introdução de substituintes ligados Ă  cadeia principal durante a sĂ­ntese, sem prejudicar a conjugação da cadeia principal.…”

“…Various vertical organic transistors, such as triode-like transistors, hot-carrier transistors, and vertical field-effect transistors, have been developed with different device architectures and operating principles. [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] These vertical transistors have been known for its high current driving capability without difficulty in making short channel, since the vertical channel length of a few hundred nanometers can be easily achieved by controlling the thickness of the organic layer deposited between the electrodes. A high on/off current ratio of 4 Â 10 4 has been demonstrated in a vertical organic transistor, called the polymer space-charge-limited transistor, operated at an extremely low operating voltage of 0.6 V. 20 The carrier holes are injected into the organic materials by the emitter electrode, passing through the openings on the base electrode, and finally being collected by the collector electrode.…”
