Abstract Pentacene, an organic molecule, is a promising material for high-performance field effect transistors due to its high charge carrier mobility in comparison to usual semiconductors. However, the charge carrier mobility is strongly dependent on the molecular orientation of pentacene in the active layer of the device, which is hard to investigate using standard techniques in a real device. Raman scattering, on the other hand, is a high-resolution technique that is sensitive to the molecular orientation. In this work, we investigated the orientation distribution of pentacene molecules in actual transistor devices by polarization-dependent Raman spectroscopy and correlated these results with the performance of the device. This study can be utilized to understand the distribution of molecular orientation of pentacene in various electronic devices and thus would help in further improving their performances.

High Charge Carrier Mobility

2D materials have emerged as new material used in electronic devices. Graphene has attract great attention due to its high charge carrier mobility and thin thickness. Different production methods have been used to produce graphene used in different electronic applications. This work highlights the validity of graphene electronic applications and drawbacks that needed to be overcome in the future. Chemical vapour deposition (CVD) grew graphene show great potential in replacing ITO in touch screen with low sheet resistance, flexibility and high transparency. Screen printed touchpad flexible keyboard can be fabricated directly from graphene inks. Graphene based touch-pad show a good conductive and flexibility while providing stable electrical performance under bending and change of humidity. Mechanical exfoliated graphene exhibits high charge carrier mobility by encapsulated with hexagonal boron nitride (h-BN).

AbstractThe critical factor that limits the efficiencies of organic electronic devices is the low charge carrier mobility which is attributed to disorder in organic films. In this work we study the effects of active film morphology on the charge transport in Organic Field Effect Transistors (OFETs). We fabricated the OFETs using different substrate temperature to grow different morphologies of C60 films by Hot Wall Epitaxy. Atomic Force Microscopy images and XRD results showed increasing grain size with increasing substrate temperature. An increase in field effect mobility was observed for different OFETs with increasing grain size in C60 films. The temperature dependence of charge carrier mobility in these devices followed the empirical relation named as Meyer-Neldel Rule and showed different activation energies for films with different degree of disorder. A shift in characteristic Meyer-Neldel energy was observed with changing C60 morphology which can be considered as an energetic disorder parameter.
