TL;DR: In this paper, a simple method for electropolymerization process that combines aniline-silane (C 6 H 5 NHC 3 H 6 Si(OMe) 3 ) surface modified indium-tin-oxide (ITO) to prepare thin, polyaniline (PANI) films with good surface coverage was presented.

TL;DR: In this paper, the response of current gain, on-to-off current ratio, and organic magnetocurrent effect (OME) to variations of temperatures and applied magnetic field (MF) for large-band-gap double-emitter nonmagnetic organic transistors (NOTs) was examined.
Abstract: This work examines the response of current gain, on-to-off current ratio, and organic magnetocurrent effect (OME) to variations of temperatures and applied magnetic field (MF) for large-band-gap double-emitter nonmagnetic organic transistors (NOTs). The NOTs showed exceptionally high on-to-off ratio up to 106. The current gain and OME were 736, and 8%, respectively. With the presence of magnetic field, these features behaved accordingly and explained.

TL;DR: In this paper, an organic transistor using a C70 sandwich emitter was proposed to reduce the leakage current and achieved an off-state leakage current that is smaller than 10-10 (minimum of 1 × 10-11 A).
Abstract: In this letter, we propose an organic transistor using a C70 sandwich emitter to reduce the leakage current. An off -state leakage current that is smaller than 10-10 (minimum of 1 × 10-11 A) can be achieved (from VCE = 0-5 V and IB = 0). The substantially reduced leakage current results in an excellent on-to-off current ratio that is up to 1.8 × 106. A small magnetocurrent effect of about 15% is obtained with an optimum emitter thickness.

TL;DR: In this article, the effects of the fullerene C70 on the device performance of a composite-emitter multilayer metal-base transistor (MBT) was studied and it was shown that the higher molecular weight leads to high common-emitters current gain β of over 252 in a wide range of collector-emistor voltage by selecting an appropriate maximum and minimum base current IB, an on-to-off current ratio 473 × 106 was achieved This is a substantial improvement over an identical MBT employing C60 having β = 8 and on-time current ratio 425
