Synthesis and Dielectric Properties of Polyimide-Tethered Polyhedral Oligomeric Silsesquioxane (POSS) Nanocomposites via POSS-diamine

Chyi Ming Leu, +2 more
- 28 Oct 2003 - 
TL;DR: Polyimide-tethered polyhedral oligomeric silsesquioxane (R7RSi8O12) nanocomposites with well-defined architectures are prepared by the copolymerization reaction of a new type of diamine monomer: POSS-diamine, 4,4'-oxydianiline (ODA), and pyromellitic dianhydride (PMDA) as mentioned in this paper.
Journal ArticleDOI

Simultaneous Use of Small‐ and Wide‐Angle X‐ray Techniques to Analyze Nanometerscale Phase Separation in Polymer Heterojunction Solar Cells

Mao-Yuan Chiu, +4 more
- 02 Jul 2008 - 
TL;DR: In this article, the effects of the sizes of the PCBM clusters and P3HT crystallites on the power conversion efficiency of bulk heterojunction solar cells were investigated. But the results were limited to a single cell with an active layer thickness of ca. 100nm.
Journal ArticleDOI

Opening an Electrical Band Gap of Bilayer Graphene with Molecular Doping

Wenjing Zhang, +11 more
- 09 Aug 2011 - 
TL;DR: This research provides a simple method to obtain a graphene bilayer transistor with a moderate on/off current ratio, which can be stably operated in air without the need to use an additional top gate.
Journal ArticleDOI

Interfacial Charge Carrier Dynamics in Core-Shell Au-CdS Nanocrystals

Ting Ting Yang, +5 more
- 10 Jun 2010 - 
TL;DR: In this article, the interfacial charge carrier dynamics for core−shell Au-CdS nanocrystals with various shell thicknesses were investigated and the electron charging of Au core and hole-enriched CdS shell was revealed with corresponding XPS analysis and photocurrent measurement.
Journal ArticleDOI

Competition between Fullerene Aggregation and Poly(3-hexylthiophene) Crystallization upon Annealing of Bulk Heterojunction Solar Cells

Wei-Ru Wu, +9 more
- 18 Jul 2011 - 
TL;DR: Optimize structural parameters, including the aggregate size and mean spacing of the PCBM aggregates, are quantitatively correlated to the device performance; a comprehensive network structure of the optimized BHJ thin film is presented.
