A turn‐on DC surface‐potential‐based drain current model for fully‐depleted poly‐Si thin film transistors

Zhu Z., Chu J., Suzhou Vocational University, CN

A turn‐on DC surface‐potential‐based drain current model for fully‐depleted polycrystalline silicon thin film transistors is developed based on the charge sheet model considering both deep and tail acceptor trap states in the grain boundary and [...]

Ink-jet Printed CdS Thin Film Transistors Fabricated In-situ by Micro-reaction

Ramos J.C., Kabir D., Mejia J.I., Martinez C.A., Quevedo-Lopez M.A., University of Texas at Dallas, US

Printed electronics has become a promising technology due to its lithography and vacuum-free processing. However, several issues remain unsolved: most printable semiconductors nowadays are organic molecules with low mobilities and poor air and moisture stability. [...]

Separation and ink formulation of high purity semiconducting single-walled carbon nanotubes with polymers for printed thin film transistors

Qian L., Zhao J.W., Cui Z., Suzhou Institute of Nano-tech and Nano-bionics, CN

In this work, a new approach to sorting SWCNTs based on regioregular poly(3-dodecylthiophene) (rr-P3DDT) has been reported. Effective separation of semiconducting-SWCNTs has been demonstrated by tuning the types of solvent, temperature and centrifugation rate. Figure [...]

Development of materials and printing methods for fabrication of thin-film transistors on flexible substrates

Zhao J.W., Gao Y.L., Gu W.B., Lin J., Chen Z., Cui Z., Suzhou Institute of Nanotech and nano-bionics, Chinese Academy of Sciences, CN

In the present work, we attempted to put together a suite of technologies for printing TFTs on flexible substates. The ink materials we investigated include optimized SCNT inks as printable semiconductors, development of composite ion-gel [...]

Optimization of Carbon Nanotube Thin-Film Transistor Fabrication

Kayastha V., Lamb J., Brewer Science, Inc, US

Carbon nanotube–based thin-film transistors have recently gained much interest from many researchers and customers for their potential in large-area electronic applications, including flexible electronics. Single-walled carbon nanotubes (SWCNTs) possess the ability to offer a high [...]

A Unified Mobility Model for Excimer Laser Annealed Complementary Thin Film Transistors Simulation

Lin H-Y, Li Y., Lin H-Y, Lee J.W., Chiu C-M, Sze S.M., Natl Nano Device Labs & Natl Chiao Tung Univ, TW

Excimer laser annealing technique has been proposed in the fabrication of low temperature polycrystalline silicon (LTPS) in the recent years, in particular for the applications to active-matrix liquid crystal display (AMLCD) [1]. In comparing with [...]
