TitleFrom Functional Polymer to Intrinsically Stretchable and Healable Transistor
AbstractPolymer materials with electronic or semi-conducting function have attracted broad academic and industrial interest for electronics applications. In this talk, we would like to present few new design concepts to address the challenges of developing high-performance charge-storage polymer electrets and intrinsically stretchable semiconducting polymer. Incorporating insulating polymers with chargeaffinity moieties into the dielectrics of transistor devices will be introduced first and demonstrate it brings transistors a memory function, which is comparable (or even better) to that of the state-of-theart metallic nano-floating gate hybrid memory devices. [1-6] On the other hand, current molecular design rules for high charge carrier mobility semiconducting polymers are unable to render the fabricated devices simultaneously stretchable and mechanically robust. To solve this problem, our concept involves introducing chemical moieties to promote dynamic non-covalent crosslinking of the conjugated polymers. These non-covalent covalent crosslinking moieties are able to undergo an energy dissipation mechanism through breakage of bonds when strain is applied, while retaining its high charge transport ability. Furthermore, we observed that the polymer can be efficiently repaired and/or healed with a simple heat and solvent treatment. These improved mechanical properties of our fabricated stretchable semiconductor enabled us to fabricate highly stretchable and high performance wearable organic transistors. This material design concept should illuminate and advance the pathways for future development of fully stretchable and healable skin-inspired wearable electronics.[7-9]

單位簡介

本系的重點研究領域包括:凝態物理、光電與奈米科學、高能與粒子物理、軟凝態物理與生物物理、原分子光學物理、及物理科學教育等。本系前身為臺灣省立師範學院理化系物理組,成立於民國三十五年(1946年)本校創校之始。民國五十一年(1962年)本系獨立成系,民國六十三年(1974年)成立物理研究所碩士班,民國八十年(1991年)成立研究所博士班。長久以來,本系肩負著培育臺灣中等學校物理科師資的重任,但也不忘在物理學術研究上求新求進步。至今本系培育出的學術人才已有一位中研院院士及近百位中研院研究員及大學教授,各行各業的高科技人材更是不勝枚舉。民國八十三年師資培育法改制後,本系已升級為尖端學術研究、科技應用研發、及中學師資培育三者齊備的系所。
