Self Assemble Monolayer

Organic field effect transistors with an active layer based on the tetracene single-crystal were fabricated. It was found that organosilane self-assemble monolayer (SAM) modified device with tetracene single-crystals gave higher mobility and on/off ratio rather than untreated device. SAM modified tetracene single-crystal transistors with parylene gate insulator showed the highest mobility of 0.66 cm2 V-1 s-1 and high on/off ratio of ~104. This finding demonstrates that SAM treatment decrease the charge leakage between source and drain which help to decrease the off current with greater extent and increase the on current slightly of the tetracene single-crystal field-effect transistors.

ABSTRACTWe proposed the magnetoelectric (ME) effect as a new function of oxides electronic devices. The ME effect is characterized by the appearance of an induced magnetization with electric field applied and also is true in the opposite way. As one of the oxides devices we proposed a new type of Josephson field effect transistor (JFET) as adopting the ME materials to a gate insulator. In such the device, considering the Fraunhofer pattern, large IC modulation was expected by the induced magnetic field. Representative ME material, Cr2O3 films were deposited on Josephson junctions which were formed bygrain boundaries in YBa2Cu3OX (YBCO) films grown on MgO substrates. The multilayered films, Cr2O3 /YBCO and Cr2O3 / Y2O3 / YBCO were studied as the model of JFET.

ABSTRACTTo benefit from the many advantages of organic semiconductors like flexibility, transparency, and small thickness, electronic devices should be entirely made from organic materials. This means, additionally to organic LEDs, organic solar cells, and organic sensors, we need organic transistors to amplify, process, and control signals and electrical power. The standard lateral organic field effect transistor (OFET) does not offer the necessary performance for many of these applications. One promising candidate for solving this problem is the vertical organic field effect transistor (VOFET). In addition to the altered structure of the electrodes, the VOFET has one additional part compared to the OFET – the source-insulator. However, the influence of the used material, the size, and geometry of this insulator on the behavior of the transistor has not yet been examined. We investigate key-parameters of the VOFET with different source insulator materials and geometries. We also present transmission electron microscopy (TEM) images of the edge area. Additionally, we investigate the charge transport in such devices using drift-diffusion simulations and the concept of a vertical organic light emitting transistor (VOLET). The VOLET is a VOFET with an embedded OLED. It allows the tracking of the local current density by measuring the light intensity distribution.We show that the insulator material and thickness only have a small influence on the performance, while there is a strong impact by the insulator geometry – mainly the overlap of the insulator into the channel. By tuning this overlap, on/off-ratios of 9x105 without contact doping are possible.

The patterned growth of crystalline rubrene films directly on electrodes is demonstrated. In addition, organic films with close packed and porous structures are locally achieved by controlling the electrode spaces, resulting in a two orders of magnitude difference in carrier mobility.
