The advantages of organic field-effect transistors (OFETs), such as low cost, flexibility and large-area fabrication, have recently attracted much attention due to their electronic applications. Practical transistors require high mobility, large on/off ratio, low threshold voltage and high stability. Development of new organic semiconductors is key to achieving these parameters. Recently, organic semiconductors have been synthesized showing comparable mobilities to amorphous-silicon-based FETs. These materials make OFETs more attractive and their applications have been attempted. New organic semiconductors resulting in high-performance FET devices are described here and the relationship between transistor characteristics and chemical structure is discussed.

“…This can be explained by the fact that physisorption of moisture or oxygen occurs at grain boundaries. 62,73 If the grain boundaries reach deep into the material, moisture or oxygen can penetrate into the semiconductor and reach the semiconductor-dielectric interface acting as electron-trapping centres. Varying the growth rate allows larger molecules to fill the gaps of the layer below, reducing the number of grain boundaries.…”

Trends in molecular design strategies for ambient stable n-channel organic field effect transistors

aIn recent years, organic semiconducting materials have enabled technological innovation in the field of flexible electronics. Substantial optimization and development of new p-conjugated materials has resulted in the demonstration of several practical devices, particularly in displays and photoreceptors.However, applications of organic semiconductors in bipolar junction devices, e.g. rectifiers and inverters, are limited due to an imbalance in charge transport. The performance of p-channel organic semiconducting materials exceeds that of electron transport. In addition, electron transport in p-conjugated materials exhibits poorer atmospheric stability and dispersive transient photocurrents due to extrinsic carrier trapping. Thus development of air stable n-channel conjugated materials is required. New classes of materials with delocalized n-doped states are under development, aiming at improvement of the electron transport properties of organic semiconductors. In this review, we highlight the basic tenets related to the stability of n-channel organic semiconductors, primarily focusing on the thermodynamic stability of anions and summarizing the recent progress in the development of air stable electron transporting organic semiconductors. Molecular design strategies are analysed with theoretical investigations.

“…For designers, the right building materials can meet the design imagination and design needs. For engineering projects, the appropriate building materials can meet the appearance and functional requirements to the maximum extent [2]. Therefore, decoration material is the material carrier of architectural engineering construction application, architectural engineering conception creation and construction project value.…”

Abstract. Through the study of GRC material and its application field, the aesthetic characteristics and functional characteristics of GRC materials are demonstrated. The decorative application and technology of GRC material in an art exhibition center are highlighted. The design, application and construction technology of GRC curtain wall and ceiling board in the interior and exterior decoration of art exhibition hall are discussed in detail. The unique advantages of GRC materials in exhibition engineering decoration are fully reflected. In practical design application, the application principle and method are summarized, and an application procedure is formed. The research proves that GRC materials in the art of building decoration engineering has an underrated advantage.
