Organic field-effect transistors (OFETs) have much attention for flexible, low cost, and ease of processing. The step-edge vertical-channel OFET (SVC-OFET) is one of vertical OFETs that can easily achieve a submicron channel using the step-edge structure [1]. On the other hand, the electrospray deposition (ESD) method is simple solution process used solution spray formed by electric field betwe...

A novel two-dimensional organic semiconductor material [1]benzothieno[3,2-b][1]benzothieno[2,1-b:3,4-b':6,5-b'':7,8-b''']tetra(benzothiophene) (BTBTTBT) which largely extends the scope of the π-conjugated framework of heteroarene through "H" configuration was synthesized and its thermal, optical and electrochemical properties were investigated. This 2D molecule enables the easy growth of single...

A series of new tetrathiafulvalene (TTF) derivatives bearing dimethoxycarbonyl and phenyl or phthalimidyl groups fused to the TTF core (6 and 15-18) has been synthesized as potential soluble semiconductor materials for organic field-effect transistors (OFETs). The electron-withdrawing substituents lower the energy of the HOMO and LUMO levels and increase the solubility and stability of the semi...

This paper presents the modeling and simulation of a low voltage pentacene organic field effect transistor (OFET), which is based on experimental data using an integrated finite element and artificial neural networks (ANN) approach. We present a model of organic field effect transistor based on neural network, this approach allows an easy way to model devices without acquiring a deep knowledge ...

A new naphthalene diimide (NDI) derivative with an asymmetric aromatic backbone of 2-tetradecylbenzo[lmn]benzo[4,5]imidazo[2,1-b][3,8]phenanthroline-1,3,6(2H)-trione (IZ0) was designed and synthesized. Low LUMO level, large energy gap, and high thermal stability are characterized for this IZ0 compound. The OFET devices based on an IZ0 semiconductor exhibit typical n-type behavior. Through conti...

The possible link between essential tremor (ET) and Parkinson's disease (PO) has been a subject of interest and debate for some time. Dating back to the first comprehensive clinical review ofET in 1949,1 there has been discussion regarding the possibility of a relationship between these two tremor disorders, with clinicians observing that ET patients have a tendency over time to develop PD. 2.3...
