Journal ArticleDOI
Engineered doping of organic semiconductors for enhanced thermoelectric efficiency
TL;DR: Reducing dopant volume is found to be as important as optimizing carrier concentration when maximizing ZT in OSCs, and this stands in sharp contrast to ISCs, for which these parameters have trade-offs.
Journal ArticleDOI
High thermal conductivity in amorphous polymer blends by engineered interchain interactions
Gun-Ho Kim,Dong-Wook Lee,Apoorv Shanker,Lei Shao,Min Sang Kwon,David W. Gidley,Jinsang Kim,Kevin P. Pipe +7 more
TL;DR: It is shown that a blend of two polymers with high miscibility and appropriately chosen linker structure can yield a dense and homogeneously distributed thermal network.
Journal ArticleDOI
Suppressing molecular motions for enhanced room-temperature phosphorescence of metal-free organic materials.
Min Sang Kwon,Youngchang Yu,Caleb Coburn,Andrew W. Phillips,Kyeongwoon Chung,Apoorv Shanker,Jaehun Jung,Gun-Ho Kim,Kevin P. Pipe,Stephen R. Forrest,Ji Ho Youk,Ji Ho Youk,Johannes Gierschner,Jinsang Kim +13 more
TL;DR: A general design rule and a method to effectively reduce radiationless transitions and hence greatly enhance phosphorescence efficiency of metal-free organic materials in a variety of amorphous polymer matrices is presented, based on the restriction of molecular motions in the proximity of embedded phosphors.
Journal ArticleDOI
CCD-based thermoreflectance microscopy: principles and applications
M. Farzaneh,Kerry Maize,D Lüerßen,D Lüerßen,J.A. Summers,P. M. Mayer,Peter E. Raad,Kevin P. Pipe,Ali Shakouri,Rajeev J. Ram,Janice Hudgings +10 more
TL;DR: In this article, the basic physical principle behind thermoreflectance as a thermography tool, discuss the experimental setup, resolutions achieved, signal processing procedures and calibration techniques, and review the current applications of CCD-based thermography in various devices.
Journal ArticleDOI
Transparent and conductive electrodes based on unpatterned, thin metal films
TL;DR: In this article, a planar heterojunction (PHJ) and bulk heter-junction organic photovoltaic (OPV) cells were investigated using transparent electrodes composed of ultrathin, unpatterned metal films.
