Vladimir A. Kolesov,Canek Fuentes-Hernandez,Wen-Fang Chou,Naoya Aizawa,Felipe A. Larrain,Ming Wang,Alberto Perrotta,Sangmoo Choi,Samuel Graham,Guillermo C. Bazan,Thuc-Quyen Nguyen,Seth R. Marder,Bernard Kippelen +12 more
TL;DR: PMA doping over a limited depth of bulk heterojunction polymeric films, in which amine-containing polymers were mixed in the solution used for film formation, enables single-layer organic photovoltaic devices, processed at room temperature, with power conversion efficiencies up to 5.9 ± 0.2% and stable performance on shelf-lifetime studies at 60 °C for at least 280 h.
Journal ArticleDOI
Elastomer-Polymer Semiconductor Blends for High-Performance Stretchable Charge Transport Networks
Dalsu Choi,Hyungchul Kim,Nils Persson,Ping-Hsun Chu,Mincheol Chang,Ji-Hwan Kang,Samuel Graham,Elsa Reichmanis +7 more
TL;DR: In this article, an inverse relationship between mechanical ductility and mobility/molecular ordering in conjugated polymer systems was determined definitively through systematic interrogation of poly(3-hexylthiophene) (P3HT) films with varied degrees of molecular ordering and associated charge transport performance.
Journal ArticleDOI
A metallization and bonding approach for high performance carbon nanotube thermal interface materials
TL;DR: These metallized and bonded VACNT films demonstrate properties which are promising for next-generation thermal interface material applications.
Journal ArticleDOI
Highly Uniform Trilayer Molybdenum Disulfide for Wafer-Scale Device Fabrication
Alexey Tarasov,Philip M. Campbell,Meng-Yen Tsai,Zohreh R. Hesabi,Janine Feirer,Samuel Graham,W. Jud Ready,Eric M. Vogel +7 more
TL;DR: In this paper, a temperature-dependent synthesis study of large-area MoS2 by direct sulfurization of evaporated Mo thin films on SiO2 is presented, where a variety of physical characterization techniques are employed to investigate the structural quality of the material.
Influence of Interfacial Mixing on Thermal Boundary Conductance Across a Chromium/Silicon
TL;DR: In this article, the effect of interdiffusion or mixing around the interface, which is generally ignored, must be taken into account when the characteristic lengths of the devices are on the order of the thickness of this mixing region.
