Photodetectors: High-Gain and Low-Driving-Voltage Photodetectors Based on Organolead Triiodide Perovskites (Adv. Mater. 11/2015)

March 12, 2015
Author(s)
Riu Dong, Yanjun Fang, Jungseok Chae, Jun Dai, Zhengguo Xiao, Qingfeng Dong, Yongbo Yuan, Andrea Centrone, Xiaocheng Zeng, Jinsong Huang
Methylammonium lead triiodide (CH3NH3PbI3) perovskite is an emerging low-cost, solution processable material which attracts great interest for enabling the fabrication of high performance optoelectronic devices such as solar cells, room temperature lasers

Near-Field Asymmetries in Plasmonic Resonators

February 12, 2015
Author(s)
Vladimir Aksyuk, Basudev Lahiri, Glenn Holland, Andrea Centrone
Surface-enhanced infrared absorption (SEIRA) spectroscopy exploits the locally enhanced field surrounding plasmonic metamaterials to increase the sensitivity of infrared spectroscopy. Light polarization and incident angle are important factors for exciting

Nanoscale Imaging and Spectroscopy of Plasmonic Modes with the PTIR technique

August 1, 2014
Author(s)
Aaron M. Katzenmeyer, Jungseok Chae, Richard Kasica, Glenn Holland, Basudev Lahiri, Andrea Centrone
The collective oscillation of conduction electrons in plasmonic nanomaterials allows the coupling of propagating light waves with nanoscale volumes of matter ("hot spots") and allows engineering their optical response from the UV to THz as a function of

Tunable electrical conductivity in metal-organic framework thin film devices

January 3, 2014
Author(s)
Albert A. Talin, Andrea Centrone, Alexandra C. Ford, Michael E. Foster, Vitalie Stavila, Paul M. Haney, Robert A. Kinney, Veronika Szalai, Farid El Gabaly, Heayoung Yoon, Francois Leonard, Mark Allendorf
We report a strategy for realizing tunable electrical conductivity in MOFs in which the nanopores are infiltrated with redox-active, conjugated guest molecules. This approach is demonstrated using thin-film devices of the MOF Cu3(BTC)2 (also known as HKUST

Controlling Thermochromism in a Photonic Block Copolymer Gel

September 26, 2012
Author(s)
Joseph J. Walish, Yin Fan , Andrea Centrone, Edwin L. Thomas
Controlling the color via temperature-induced changes of self-assembled photonic materials is important for their application in sensors and displays. The thermochromic behavior of a PS-P2VP photonic gel was studied (UV-VIS, FTIR) and found to originate
