In this work, we demonstrate how engineering the dielectric layer based on high-k polyvinylidene fluoride (PVDF)-based polymers can lead to a drastic reduction of device driving voltages and the improvement of its optoelectronic properties. We first investigated the morphology and the dielectric response of these polymer dielectrics in terms of polymer (P(VDF-TrFE) and P(VDF-TrFE-CFE)) and solvent content (cyclopentanone, methylethylketone). Implementing these high-k PVDF-based dielectrics enabled low-bias ambipolar organic light emitting transistors, with reduced threshold voltages (<20 V) and enhanced light output (compared to conventional polymer reference), along with an overall improvement of the device efficiency. Further, we preliminary transferred these fluorinated high-k dielectric films onto a plastic substrate to enable flexible light emitting transistors. These findings hold potential for broader exploitation of the OLET platform, where the device can now be driven by commercially available electronics, thus enabling flexible low-bias organic electronic devices.Peer reviewe
C.S. Lewis: adaptations of life and work
No full textThe author discusses film representations of the life of C.S. Lewis – a famous English Christian writer. She also focuses on adaptations (that include books, television and cinema) of his most famous series The Chronicles of Narnia – series that for already sixty years have been published all over the world
The Nurse of Elfland: Lizzie Endicott and C.S. Lewis
Full text linkIn Surprised by Joy, C.S. Lewis introduced Lizzie Endicott as the first of two other blessings in his childhood, even before his introduction of Warnie. But apart from his abbreviated 136-word biography, very little is known about the nurse who introduced Lewis to faery tales. Based on the Lewis Family Papers, genealogical research, and personal interviews with Lizzie’s relatives, this article introduces Lizzie to the world of Lewismania. It also suggests various ways in which Lizzie influenced the man and the author that C.S. Lewis became, as well as the mythical worlds he created and Lewis’s anonymous tributes to her
A study of upwelling characteristics around Taiwan
No full textThe study aims to discuss the characteristics and seasonal variabilities of the oceanic upwelling region around Taiwan. The study using satellite data for recognizing the upwellings from sea surface temperature (SST) distribution. Upwelling is a current flowing from deeper ocean onto surface layer. It is often driven by tide, variation of topography and wind, seasonal winds particularly. Upwelling currents bring abundance of nutrients onto surface layer, which stimulate plankton growth forming an upwelling ecosystem.
From the study, three upwelling zones around Taiwan have been identified, i.e. Taiwan Bank Upwelling zone(TBU), Penghu Upwelling zone (PHU), and the northeast Taiwan Upwelling zone (NEU). The summer monsoon in Taiwan is mainly associated with the Asian monsoon system, which is a southwesterly wind system consistently blow into Taiwan Strait between June to September. South China Sea Current (SCS) is driven by this southwesterly wind flows into the Taiwan Strait. The SCS current meets uplifting topography in Penghu area. Cold deep water move up to the surface layer, and low SST can be observed in TBU and PHU. Kuroshio Current in the western Pacific flow through the east coast of Taiwan persistently. After collision into the East China Sea (ECS) continental shelf, Kuroshio Current uplift into ECS forming the upwelling system in the area of northeast Taiwan called NEU. These three upwelling zones have their own seasonal variabilities and characteristics will be discussed
